Crate rustc_builtin_macros

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 🔒

cfg_select 🔒

clone 🔒

cmdline_attrs

Attributes injected into the crate root from command line using -Z crate-attr.

coerce_pointee 🔒

compile_error 🔒

concat 🔒

concat_bytes 🔒

const_param_ty 🔒

contracts

copy 🔒

debug 🔒

default 🔒

define_opaque 🔒

derive 🔒

deriving 🔒

The compiler code necessary to implement the #[derive] extensions.

diagnostics 🔒

edition_panic 🔒

eii 🔒

env 🔒

eq 🔒

format 🔒

format_foreign 🔒

from 🔒

gca 🔒

generic 🔒

Some code that abstracts away much of the boilerplate of writing derive instances for traits. Among other things it manages getting access to the fields of the 4 different sorts of structs and enum variants, as well as creating the method and impl ast instances.

global_allocator 🔒

hash 🔒

iter 🔒

log_syntax 🔒

offload 🔒

ord 🔒

partial_eq 🔒

partial_ord 🔒

pattern_type 🔒

proc_macro_harness

reborrow 🔒

rustdoc_skip_body 🔒

The expansion from a function when the code would not compile with rustdoc: so if cfg(doc), expands to a loop {}.

source_util 🔒

The implementation of built-in macros which relate to the file system.

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_binder_constraints 🔒

test_harness

trace_macros 🔒

util

view_type 🔒

Macros

path_std 🔒

pathvec 🔒

Structs

BuiltinDerive 🔒

Functions

assert_ty_bounds 🔒

call_discriminant_value 🔒

Constructs an expression that calls the discriminant_value intrinsic.

call_unreachable 🔒

Constructs an expression that calls the unreachable intrinsic.
