decoder 🔒

def_path_hash_map 🔒

encoder 🔒

table 🔒

Macros

define_tables 🔒

Define LazyTables and TableBuilders at the same time.

Structs

AttrFlags

CrateDep 🔒

CrateHeader 🔒

Serialized crate metadata.

CrateRoot 🔒

Serialized .rmeta data for a crate.

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.

SpanTag 🔒

A span tag byte encodes a bunch of data, so that we can cut out a few extra bytes from span encodings (which are very common, for example, libcore has ~650,000 unique spans and over 1.1 million references to prior-written spans).

TableBuilders 🔒

TraitImpls 🔒

VariantData 🔒

Enums

LazyState 🔒

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

SpanKind 🔒

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 🔒
