From d9508a1fd2bdbc2f7c4e2ee28503f15487fdc8ce Mon Sep 17 00:00:00 2001 From: Nicholas Nethercote Date: Fri, 2 Feb 2024 15:44:22 +1100 Subject: Make `Emitter::emit_diagnostic` consuming. All the other `emit`/`emit_diagnostic` methods were recently made consuming (e.g. #119606), but this one wasn't. But it makes sense to. Much of this is straightforward, and lots of `clone` calls are avoided. There are a couple of tricky bits. - `Emitter::primary_span_formatted` no longer takes a `Diagnostic` and returns a pair. Instead it takes the two fields from `Diagnostic` that it used (`span` and `suggestions`) as `&mut`, and modifies them. This is necessary to avoid the cloning of `diag.children` in two emitters. - `from_errors_diagnostic` is rearranged so various uses of `diag` occur before the consuming `emit_diagnostic` call. --- compiler/rustc_codegen_ssa/src/back/write.rs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'compiler/rustc_codegen_ssa/src/back') diff --git a/compiler/rustc_codegen_ssa/src/back/write.rs b/compiler/rustc_codegen_ssa/src/back/write.rs index 4211f875dd0..9b24339d255 100644 --- a/compiler/rustc_codegen_ssa/src/back/write.rs +++ b/compiler/rustc_codegen_ssa/src/back/write.rs @@ -1810,7 +1810,7 @@ impl Translate for SharedEmitter { } impl Emitter for SharedEmitter { - fn emit_diagnostic(&mut self, diag: &rustc_errors::Diagnostic) { + fn emit_diagnostic(&mut self, diag: rustc_errors::Diagnostic) { let args: FxHashMap = diag.args().map(|(name, arg)| (name.clone(), arg.clone())).collect(); drop(self.sender.send(SharedEmitterMessage::Diagnostic(Diagnostic { -- cgit 1.4.1-3-g733a5
