Module rustc_metadata::rmeta

Re-exports

• pub use decoder::provide_extern;
• pub use encoder::encode_metadata;
• pub use encoder::EncodedMetadata;

Modules

• decoder 🔒
• def_path_hash_map 🔒
• encoder 🔒
• table 🔒

Macros

• define_tables 🔒
  Define LazyTables and TableBuilders at the same time.

Structs

• AttrFlags
• CrateDep 🔒
• CrateRoot 🔒
  Serialized metadata for a crate. When compiling a proc-macro crate, we encode many of the LazyArray<T> fields as Lazy::empty(). This serves two purposes:
• IncoherentImpls 🔒
• LazyArray 🔒
  A list of lazily-decoded values.
• LazyTable 🔒
  A list of lazily-decoded values, with the added capability of random access.
• LazyTables 🔒
• LazyValue 🔒
  A value of type T referred to by its absolute position in the metadata, and which can be decoded lazily.
• ProcMacroData 🔒
• RawDefId 🔒
  On-disk representation of DefId. This creates a type-safe way to enforce that we remap the CrateNum between the on-disk representation and the compilation session.
• TableBuilders 🔒
• TraitImpls 🔒
• VariantData 🔒

Enums

• LazyState 🔒
  Encoding / decoding state for Lazys (LazyValue, LazyArray, and LazyTable).

Constants

• METADATA_HEADER
  Metadata header which includes METADATA_VERSION.
• METADATA_VERSION 🔒
  Metadata encoding version. N.B., increment this if you change the format of metadata such that the rustc version can’t be found to compare with rustc_version().
• SYMBOL_OFFSET 🔒
• SYMBOL_PREINTERNED 🔒
• SYMBOL_STR 🔒
• TAG_PARTIAL_SPAN 🔒
• TAG_VALID_SPAN_FOREIGN 🔒
• TAG_VALID_SPAN_LOCAL 🔒

Functions

• provide
• rustc_version 🔒

Type Definitions

• ExpnDataTable 🔒
• ExpnHashTable 🔒
• SyntaxContextTable 🔒
