Crate rustc_builtin_macros

This crate contains implementations of built-in macros and other code generating facilities injecting code into the crate before it is lowered to HIR.

Modules

• alloc_error_handler 🔒
• asm
• assert 🔒
• autodiff 🔒
  This module contains the implementation of the #[autodiff] attribute. Currently our linter isn’t smart enough to see that each import is used in one of the two configs (autodiff enabled or disabled), so we have to add cfg’s to each import. FIXME(ZuseZ4): Remove this once we have a smarter linter.
• cfg 🔒
  The compiler code necessary to support the cfg! extension, which expands to a literal true or false based on whether the given cfg matches the current compilation environment.
• cfg_accessible 🔒
  Implementation of the #[cfg_accessible(path)] attribute macro.
• cfg_eval 🔒
• cmdline_attrs
  Attributes injected into the crate root from command line using -Z crate-attr.
• compile_error 🔒
• concat 🔒
• concat_bytes 🔒
• concat_idents 🔒
• derive 🔒
• deriving 🔒
  The compiler code necessary to implement the #[derive] extensions.
• edition_panic 🔒
• env 🔒
• errors 🔒
• format 🔒
• format_foreign 🔒
• global_allocator 🔒
• log_syntax 🔒
• pattern_type 🔒
• proc_macro_harness
• source_util 🔒
• standard_library_imports
• test 🔒
  The expansion from a test function to the appropriate test struct for libtest Ideally, this code would be in libtest but for efficiency and error messages it lives here.
• test_harness
• trace_macros 🔒
• util
