From 899cb40809a85eb9d89f6da3268713b83175360a Mon Sep 17 00:00:00 2001 From: Nicholas Nethercote Date: Fri, 23 Feb 2024 10:20:45 +1100 Subject: [PATCH] Rename `DiagnosticBuilder` as `Diag`. Much better! Note that this involves renaming (and updating the value of) `DIAGNOSTIC_BUILDER` in clippy. --- compiler/rustc_ast_lowering/src/errors.rs | 4 +- compiler/rustc_ast_passes/src/errors.rs | 7 +-
