Update ui test suite to use dyn 2019-05-28 14:46:13 -04:00			`#![allow(bare_trait_objects)]`

Change a few error messages to give code suggestions PR #24242 added the ability to the compiler to directly give suggestions about how to modify code to fix an error. The new errors look like this: foobar.rs:5:12: 5:25 error: expected a path on the left-hand side of `+`, not `&'static Copy` [E0178] foobar.rs:5 let x: &'static Copy + 'static; ^~~~~~~~~~~~~ foobar.rs:5:12: 5:35 help: try adding parentheses (per RFC 438): foobar.rs: let x: &'static (Copy + 'static); foobar.rs:2:13: 2:23 error: cast to unsized type: `&_` as `core::marker::Copy` foobar.rs:2 let x = &1 as Copy; ^~~~~~~~~~ foobar.rs:2:19: 2:23 help: try casting to a reference instead: foobar.rs: let x = &1 as &Copy; foobar.rs:7:24: 7:25 error: expected expression, found `;` foobar.rs:7 let x = box (1 + 1); ^ foobar.rs:7:13: 7:16 help: try using `box()` instead: foobar.rs: let x = box() (1 + 1); This also modifies compiletest to give the ability to directly test suggestions given by error messages. 2015-04-21 21:13:42 +12:00			`fn main() {`

Refactor dyn-compatibility error and suggestions This CL makes a number of small changes to dyn compatibility errors: - "object safety" has been renamed to "dyn-compatibility" throughout - "Convert to enum" suggestions are no longer generated when there exists a type-generic impl of the trait or an impl for `dyn OtherTrait` - Several error messages are reorganized for user readability Additionally, the dyn compatibility error creation code has been split out into functions. cc #132713 cc #133267 2024-11-20 14:19:36 -08:00			`//~^ ERROR is not dyn compatible`
