It's a large type -- 176 bytes on 64-bit. And it's passed around and
returned from a lot of functions, including within PResult.
This commit boxes it, which reduces memory traffic. In particular,
`PResult` shrinks to 16 bytes in the best case; this reduces instruction
counts by up to 2% on various workloads.
This moves the two methods from the `EmitterWriter` impl to trait
default methods in the `Emitter` trait so that they can be re-used by
the `AnnotateSnippetEmitterWriter`.
Closes#61810
An initial refactoring before working on #61809.
This moves the whole block into a method so that it can be reused in the
annotate-snippet output. It's already used in the new emitter, but
there's no UI tests with suggestions included in this PR.
A first look at some UI tests with suggestions showed that there's some
more work to do in [annotate-snippet-rs][annotate-snippet-rs] before the
new output is closer to the current one.
The proper name of the library is `annotate-snippet`, not `annotate-rs`,
this commit should get rid of any confusing `AnnotateRs` names.
1. Renames `annotate_rs_emitter.rs` to
`annotate_snippet_emitter_writer.rs` so that the difference between the
`Emitter` trait and the implementers is more clear.
2. Renames `AnnotateRsEmitterWriter` to `AnnotateSnippetEmitterWriter`
3. Renames `HumanReadableErrorType::AnnotateRs` to `HumanReadableErrorType::AnnotateSnippet`
