Add `do yeet` expressions to allow experimentation in nightly

2022-05-01T00:40:27+00:00

Using an obviously-placeholder syntax. An RFC would still be needed before this could have any chance at stabilization, and it might be removed at any point. But I'd really like to have it in nightly at least to ensure it works well with try_trait_v2, especially as we refactor the traits.

errors: `span_suggestion` takes `impl ToString`

2022-04-29T01:05:20+00:00

Change `span_suggestion` (and variants) to take `impl ToString` rather than `String` for the suggested code, as this simplifies the requirements on the diagnostic derive. Signed-off-by: David Wood

rustc_ast: Harmonize delimiter naming with `proc_macro::Delimiter`

Avoid producing `NoDelim` values in `TokenCursorFrame`.

Shrink `Nonterminal`.

By heap allocating the argument within `NtPath`, `NtVis`, and `NtStmt`. This slightly reduces cumulative and peak allocation amounts, most notably on `deep-vector`.

errors: implement fallback diagnostic translation

2022-04-05T06:01:02+00:00

This commit updates the signatures of all diagnostic functions to accept types that can be converted into a `DiagnosticMessage`. This enables existing diagnostic calls to continue to work as before and Fluent identifiers to be provided. The `SessionDiagnostic` derive just generates normal diagnostic calls, so these APIs had to be modified to accept Fluent identifiers. In addition, loading of the "fallback" Fluent bundle, which contains the built-in English messages, has been implemented. Each diagnostic now has "arguments" which correspond to variables in the Fluent messages (necessary to render a Fluent message) but no API for adding arguments has been added yet. Therefore, diagnostics (that do not require interpolation) can be converted to use Fluent identifiers and will be output as before.

Suggest `i += 1` when we see `i++` or `++i` Closes #83502 (for `i++` and `++i`; `--i` should be covered by #82987, and `i--` is tricky to handle). This is a continuation of #83536. r? `@estebank`

suggest wrapping single-expr blocks in square brackets Suggests a fix in cases like: ```diff - const A: [i32; 1] = { 1 }; + const A: [i32; 1] = [ 1 ]; ^ ^ ``` Also edit the message for the same suggestion in the parser (e.g. `{ 1, 2 }`). Fixes #95289
