Modules

definitions

For each definition, we track the following data. A definition here is defined somewhat circularly as “something with a DefId”, but it generally corresponds to things like structs, enums, etc. There are also some rather random cases (like const initializer expressions) that are mostly just leftovers.

diagnostic_items

hir 🔒

hir_id

intravisit

HIR walker for walking the contents of nodes.

lang_items

Defines lang items.

pat_util

stable_hash_impls 🔒

target 🔒

This module implements some validity checks for attributes. In particular it verifies that #[inline] and #[repr] attributes are attached to items that actually support them and if there are conflicts between multiple such attributes attached to the same item.

weak_lang_items

Validity checking for weak lang items

Macros

arena_types

This higher-order macro declares a list of types which can be allocated by Arena. Note that all Copy types can be allocated by default and need not be specified here.

HashStableContext

Requirements for a StableHashingContext to be used in this crate. This is a hack to allow using the HashStable_Generic derive macro instead of implementing everything in rustc_middle.
