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 🔒

contracts

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

Statics

DEFAULT_LOCALE_RESOURCE

Raw content of Fluent resource for this crate, generated by fluent_messages macro, imported by rustc_driver to include all crates’ resources in one bundle.
