From d10919ff383374549424dce3f95a30c695035253 Mon Sep 17 00:00:00 2001 From: Lukas Bergdoll Date: Mon, 7 Apr 2025 19:30:51 +0200 Subject: [PATCH 01/15] Explicitly export core and std macros Currently all core and std macros are automatically added to the prelude via #[macro_use]. However a situation arose where we want to add a new macro `assert_matches` but don't want to pull it into the standard prelude for compatibility reasons. By explicitly exporting the macros found in the core and std crates we get to decide on a per macro basis and can later add them via the rust_20xx preludes. --- .../src/standard_library_imports.rs | 2 +- library/core/src/prelude/v1.rs | 53 +++++++++++++++++- library/proc_macro/src/bridge/symbol.rs | 4 +- library/std/src/prelude/v1.rs | 55 +++++++++++++++++-- 4 files changed, 105 insertions(+), 9 deletions(-) diff --git a/compiler/rustc_builtin_macros/src/standard_library_imports.rs b/compiler/rustc_builtin_macros/src/standard_library_imports.rs index 682e7c9b17ae8..2617a24ebb4a7 100644 --- a/compiler/rustc_builtin_macros/src/standard_library_imports.rs +++ b/compiler/rustc_builtin_macros/src/standard_library_imports.rs @@ -43,7 +43,7 @@ pub fn inject( let item = cx.item( span, - thin_vec![cx.attr_word(sym::macro_use, span)], + ast::AttrVec::new(), ast::ItemKind::ExternCrate(None, Ident::new(name, ident_span)), );
