Modules

• arena 🔒
• def
• def_id
• def_path_hash_map
• 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.

Structs

• Arena

Enums

• MethodKind
• Target

Traits

• ArenaAllocatable
• 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.
