Fix #53525 - Unify E0243, E0244, E0087, E0088, E0089, and E0090 into E0107 #53584

matthew-russo · 2018-08-22T01:40:37Z

This pr merges all errors related to too many or too few generic arguments in types and functions. E0243, E0244, E0087, E0088, E0089, E0090 errors will no longer be emitted and E0107 will be used instead.

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @pnkfelix (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

[00:47:09] {"message":"the trait `bar` cannot be made into an object","code":{"code":"E0038","explanation":"\nTrait objects like `Box<Trait>` can only be constructed when certain\nrequirements are satisfied by the trait in question.\n\nTrait objects are a form of dynamic dispatch and use a dynamically sized type\nfor the inner type. So, for a given trait `Trait`, when `Trait` is treated as a\ntype, as in `Box<Trait>`, the inner type is 'unsized'. In such cases the boxed\npointer is a 'fat pointer' that contains an extra pointer to a table of methods\n(among other things) for dynamic dispatch. This design mandates some\nrestrictions on the types of traits that are allowed to be used in trait\nobjects, which are collectively termed as 'object safety' rules.\n\nAttempting to create a trait object for a non object-safe trait will trigger\nths called with unparametrized substitutions\n(i.e., substitutions where none of the substituted types are themselves\nparametrized).\n\nHowever, with trait objects we have to make a table containing _every_ object\nthat implements the trait. Now, if it has type parameters, we need to add\nimplementations for every type that implements the trait, and there could\ntheoretically be an infinite number of types.\n\nFor example, with:\n\n```\ntrait Trait {\n    fn foo<T>(&self, on: T);\n    // more methods\n}\n\nimpl Trait for String {\n    fn foo<T>(&self, on: T) {\n        // implementation 1\n    }\n}\n\nimpl Trait for u8 {\n    fn foo<T>(&self, on: T) {\n        // implementation 2\n    }\n}\n\n// 8 more implementations\n```\n\nNow, if we have the following code:\n\n```compile_fail,E0038\n# trait Trait { fn foo<T>(&self, on: T); }\n# impl Trait for String { fn foo<T>(&self, on: T) {} }\n# impl Trait for u8 { fn foo<T>(&self, on: T) {} }\n# impl Trait for bool { fn foo<T>(&self, on: T) {} }\n# // etc.\nfn call_foo(thing: Box<Trait>) {\n    thing.foo(true); // this could be any one of the 8 types above\n    thing.foo(1);\n    thing.foo(\"hello\");\n}\n```\n\nWe don't just need to create a table of all implementations of all methods of\n`Trait`, we need to create such a table, for each different type fed to\n`foo()`. In this case this turns out to be (10 types implementing `Trait`)*(3\ntypes being fed to `foo()`) = 30 implementations!\n\nWith real world traits these numbers can grow drastically.\n\nTo fix this, it is suggested to use a `where Self: Sized` bound similar to the\nfix for the sub-error above if you do not intend to calthat do not take a `self` parameter can't be called since there won't be\na way to get a pointer to the method table for them.\n\n```\ntrait Foo {\n    fn foo() -> u8;\n}\n```\n\nThis could be called as `<Foo as Foo>::foo()`, which would not be able to pick\nan implementation.\n\nAdding a `Self: Sized` bound to these methods will generally make this compile.\n\n```\ntrait Foo {\n    fn foo() -> u8 where Self: Sized;\n}\n```\n\n### The trait cannot contain associated constants\n\nJust like static functions, associated constants aren't stored on the method\ntable. If the trait or any subtrait contain an associated constant, they cannot\nbe made into an object.\n\n```compile_fail,E0038\ntrait Foo {\n    const X: i32;\n}\n\nimpl Foo {}\n```\n\nA simple workaround is to use a helper method instead:\n\n```\ntrait Foo {\n    fn x(&self) -> i32;\n}\n```\n\n### The trait cannot use `Self` as a type parameter in the supertrait listing\n\nThis is similar to the second sub-error, but subtler. It happens in situations\nlike the following:\n\n```compile_fail\ntrait Super<A> {}\n\ntrait Trait: Super<Self> {\n}\n\nstruct Foo;\n\nimpl Super<Foo> for Foo{}\n\nimpl Trait for Foo {}\n```\n\nHere, the supertrait might have methods as follows:\n\n```\ntrait Super<A> {\n    fn get_a(&self) -> A; // note that this is object safe!\n}\n```\n\nIf the trait `Foo` was deriving from something like `Super<String>` or\n`Super<T>` (where `Foo` itself is `Foo<T>`), this is okay, because given a type\n`get_a()` will definitely return an object of that type.\n\nHowever, if it derives from `Super<Self>`, even though `Super` is object safe,\nthe method `get_a()` r: Bar<'a>, // error: wrong number of lifetime arguments:\n                  //        expected 0, found 1\n}\n```\n\n```compile_fail,E0107\nstruct Foo<T> { x: T }\n\nstruct Bar { x: Foo }             // error: wrong number of type arguments:\n                                  //        expected 1, found 0\nstruct Baz<S, T> { x: Foo<S, T> } // error: wrong number of type arugemtns:\n                                  //        expected 1, found 2\n```\n\n```compile_fail,E0107\nfn foo<T, U>(x: T) {}\n\nfn main() {\n    let x: bool = true;\n    foo::<f64>(x);           // error: wrong number of type arguments:\n                             //        expected 2, found 1\n    foo::<f64, f64, i32>(x); // error: wrong number of type arguments:\n                             //        expected 2, found 3\n}\n```\n\n```compile_fail,E0088\nfn f<'a>() {}\n\nfn main() {\n    f()                 // error: wrong number of lifetime arguments:\n                        //        expected 1, found 0\n    f::<'static, 'b>() // error: wrong number of lifetime arguments:\n                        //        expected 0, found 2\n}\n```\n\n"},"level":"error","spans":[{"file_name":"/checkout/src/test/ui/typeck/typeck-builtin-bound-type-parameters.rs","byte_start":800,"byte_end":802,"line_start":20,"line_end":20,"column_start":30,"column_end":32,"is_primary":true,"text":[{"text":"struct MyStruct2<'a, T: Copy<'a>>;","highlight_start":30,"highlight_end":32}],"label":"unexpected lifetime argument","suggested_replacement":null,"suggestion_applicability":null,"expansion":null}],"children":[],"rendered":"error[E0107]: wrong number of lifetime arguments: expecrendered":"error: aborting due to previous error\n\n"}

This is looking good so far! It looks like there are still some tests failing, which you'll need to update. Also, it's not linking the committer for each commit with your GitHub profile, which you might want to fix with a rebase.

Since we're going to be getting const parameters fairly soon, it's easier just to call them "generic arguments" rather than "type or lifetime parameters".

These examples can be in the same code block. You don't need an example of less than/greater than the expected number for every single position — maybe one example for each position (type, function call, method call).

If you put the pull request description in the first comment (and title), it helps people to tell what the pull request is doing, at a glance, too. I think you'll need to put "Fix #53525" in the first comment for GitHub to automatically close the issue when this is merged.

matthew-russo · 2018-08-22T13:08:43Z

Noted. Will probably not get a chance to update this before this evening

varkor · 2018-08-22T18:21:58Z

If you could also rebase so that the relevant changes were together, that would make for a cleaner history — maybe a commit for:

Merging error code descriptions into E0107 and adding "no longer emitted" messages to the others.
Removing GenericArgMismatchErrorCode.
Updating all UI tests with the updated diagnostics.

Thanks!

matthew-russo · 2018-08-23T02:32:12Z

@varkor I rebased and changed order of code. Honestly not positive if I got it right since was my first time reordering git commits. Also still haven't fixed all failing errors so will do that tomorrow and will need to rebase again. Will update when its ready to review

[00:46:53] {"message":"the trait bound `dyn bar: bar` is not satisfied","code":{"code":"E0277","explanation":"\nYou tried to use a type which doesn't implement some trait in a place which\nexpected that trait. Erroneous code example:\n\n```compile_fail,E0277\n// here we declare the Foo trait with a bar method\ntrait Foo {\n    fn bar(&self);\n}\n\n// we now declare a function which takes an object implementingn add a `where Self: Sized` bound\non them to mark them as explicitly unavailable to trait objects. The\nfunctionality will still be available to all other implementers, including\n`Box<Trait>` which is itself sized (assuming you `impl Trait for Box<Trait>`).\n\n```\ntrait Trait {\n    fn foo(&self) -> Self where Self: Sized;\n    // more functions\n}\n```\n\nNow, `foo()` can no longer be called on a trait object, but you will now be\nallowed to make a trait object, and that will be able to call any object-safe\nmethods. With such a bound, one can still call `foo()` on types implementing\nthat trait that aren't behind trait objects.\n\n### Method has generic type parameters\n\nAs mentioned before, trait objects contain pointers to method tables. So, if we\nhave:\n\n```\ntrait Trait {\n    fn foo(&self);\n}\n\nimpl Trait for String {\n    fn foo(&self) {\n        // implementation 1\n    }\n}\n\nimpl Trait for u8 {\n    fn foo(&self) {\n        // implementation 2\n    }\n}\n// ...\n```\n\nAt compile time each implementation of `Trait` will produce a table containing\nthe various methods (and other items) related to the implementation.\n\nThis works fine, but when the method gains generic parameters, we can have a\nproblem.\n\nUsually, generic parameters get _monomorphized_. For example, if I have\n\n```\nfn foo<T>(x: T) {\n    // ...\n}\n```\n\nThe machine code for `foo::<u8>()`, `foo::<bool>()`, `foo::<String>()`, or any\nother type substitution is different. Hence the compiler generates the\nimplementation on-demand. If you call `foo()` with a `bool` parameter, the\ncompiler will only generate code for `foo::<bool>()`. Whenwhere Self: Sized {\n\n}\n```\n\nWe cannot create an object of type `Box<Foo>` or `&Foo` since in this case\n`Self` would not be `Sized`.\n\nGenerally, `Self : Sized` is used to indicate that the trait should not be used\nas a trait object. If the trait comes from your own crate, consider removing\nthis restriction.\n\n### Method references the `Self` type in its arguments or return type\n\nThis happens when a trait has a method like the following:\n\n```\ntrait Trait {\n    fn foo(&self) -> Self;\n}\n\nimpl Trait for String {\n    fn foo(&self) -> Self {\n        \"hi\".to_owned()\n    }\n}\n\nimpl Trait for u8 {\n    fn foo(&self) -> Self {\n        1\n    }\n}\n```\n\n(Note that `&self` and `&mut self` are okay, it's additional `Self` types which\ncause this problem.)\n\nIn such a case, the compiler cannot predict the return type of `foo()` in a\nsituation like the following:\n\n```compile_fail\ntrait Trait {\n    fn foo(&self) -> Self;\n}\n\nfn call_foo(x: Box<Trait>) {\n    let y = x.foo(); // What type is y?\n    // ...\n}\n```\n\nIf only some methods aren't object-safe, you can add a `where Self: Sized` bound\non them to mark them as explicitly unavailable to trait objects. The\nfunctionality will still be available to all other implementers, including\n`Box<Trait>` which is itself sized (assuming you `impl Trait for Box<Trait>`).\n\n```\ntrait Trait {\n    fn foo(&self) -> Self where Self: Sized;\n    // more functions\n}\n```\n\nNow, `foo()` can no longer be called on a trait object, but you will now be\nallowed to make a trait object, and that will be able to call any object-safe\nmethods. With such a bound, one can and there could\ntheoretically be an infinite number of types.\n\nFor example, with:\n\n```\ntrait Trait {\n    fn foo<T>(&self, on: T);\n    // more methods\n}\n\nimpl Trait for String {\n    fn foo<T>(&self, on: T) {\n        // implementation 1\n    }\n}\n\nimpl Trait for u8 {\n    fn foo<T>(&self, on: T) {\n        // implementation 2\n    }\n}\n\n// 8 more implementations\n```\n\nNow, if we have the following code:\n\n```compile_fail,E0038\n# trait Trait { fn foo<T>(&self, on: T); }\n# impl Trait for String { fn foo<T>(&self, on: T) {} }\n# impl Trait for u8 { fn foo<T>(&self, on: T) {} }\n# impl Trait for bool { fn foo<T>(&self, on: T) {} }\n# // etc.\nfn call_foo(thing: Box<Trait>) {\n    thing.foo(true); // this could be any one of the 8 types above\n    thing.foo(1);\n    thing.foo(\"hello\");\n}\n```\n\nWe don't just need to create a table of all implementations of all methods of\n`Trait`, we need to create such a table, for each different type fed to\n`foo()`. In this case this turns out to be (10 types implementing `Trait`)*(3\ntypes being fed to `foo()`) = 30 implementations!\n\nWith real world traits these numbers can grow drastically.\n\nTo fix this, it is suggested to use a `where Self: Sized` bound similar to the\nfix for the sub-error above if you do not intend to call the method with type\nparameters:\n\n```\ntrait Trait {\n    fn foo<T>(&self, on: T) where Self: Sized;\n    // more methods\n}\n```\n\nIf this is not an option, consider replacing the type parameter with another\ntrait object (e.g. if `T: OtherTrait`, use `on: Box<OtherTrait>`). If the number\nof types you intend to feed to this method is li0:46:53] - error[E0244]: wrong number of type arguments: expected 0, found 1

varkor · 2018-08-23T11:19:42Z

@mcr431: that looks good, thanks! (I think git has recorded users for the author/committer for your commits, which is why it's showing up as two different users on here — it's not a huge problem, but it might mean you're not attributed when the pull request gets merged — if you didn't find the rebase too much of a pain, you could try overwriting the author for each commit so that the right name/email was being used 😄.)

matthew-russo · 2018-08-23T12:56:46Z

Yeah I had set up a dummy account to test stuff and forgot to switch it back. When rebasing with fixed test cases I'll make sure it has proper author

Ah, the snippets in the diagnostics are also run by the test-suite, so you'll need to update the compile_fail error code so that it matches the new code E0107.
