Move eager translation to a method on `Diag`

2025-04-17T01:38:59+00:00

This will allow us to eagerly translate messages on a top-level diagnostic, such as a `LintDiagnostic`. As a bonus, we can remove the awkward closure passed into Subdiagnostic and make better use of `Into`.

Teach structured errors to display short `Ty`

2025-02-25T16:56:03+00:00

Make it so that every structured error annotated with `#[derive(Diagnostic)]` that has a field of type `Ty<'_>`, the printing of that value into a `String` will look at the thread-local storage `TyCtxt` in order to shorten to a length appropriate with the terminal width. When this happen, the resulting error will have a note with the file where the full type name was written to. ``` error[E0618]: expected function, found `((..., ..., ..., ...), ..., ..., ...)`` --> long.rs:7:5 | 6 | fn foo(x: D) { //~ `x` has type `(... | - `x` has type `((..., ..., ..., ...), ..., ..., ...)` 7 | x(); //~ ERROR expected function, found `(... | ^-- | | | call expression requires function | = note: the full name for the type has been written to 'long.long-type-14182675702747116984.txt' = note: consider using `--verbose` to print the full type name to the console ```

Move some `Map` methods onto `TyCtxt`.

2025-02-17T02:21:02+00:00

The end goal is to eliminate `Map` altogether. I added a `hir_` prefix to all of them, that seemed simplest. The exceptions are `module_items` which became `hir_module_free_items` because there was already a `hir_module_items`, and `items` which became `hir_free_items` for consistency with `hir_module_free_items`.

introduce `LateParamRegionKind`

Re-export more `rustc_span::symbol` things from `rustc_span`.

2024-12-18T02:38:53+00:00

`rustc_span::symbol` defines some things that are re-exported from `rustc_span`, such as `Symbol` and `sym`. But it doesn't re-export some closely related things such as `Ident` and `kw`. So you can do `use rustc_span::{Symbol, sym}` but you have to do `use rustc_span::symbol::{Ident, kw}`, which is inconsistent for no good reason. This commit re-exports `Ident`, `kw`, and `MacroRulesNormalizedIdent`, and changes many `rustc_span::symbol::` qualifiers in `compiler/` to `rustc_span::`. This is a 200+ net line of code reduction, mostly because many files with two `use rustc_span` items can be reduced to one.
