Structs

BlobDecodeContext 🔒

Decode context used when we just have a blob of metadata from which we have to decode a header and CrateRoot. After that, MetadataDecodeContext can be used. Most notably, [BlobDecodeContext] doesn’t implement SpanDecoder

CrateMetadata 🔒

DecodeIterator 🔒

ImportedSourceFile 🔒

Holds information about a rustc_span::SourceFile imported from another crate. See imported_source_file() for more information.

MetadataBlob 🔒

A reference to the raw binary version of crate metadata. This struct applies MemDecoder’s validation when constructed so that later constructions are guaranteed to succeed.

MetadataDecodeContext 🔒

This is the decode context used when crate metadata was already read. Decoding of some types, like Span require some information to already been read. Can be constructed from a TyCtxt and CrateMetadata (see impls of the MetaDecoder trait).

Traits

LazyDecoder 🔒

This trait abstracts over decoders that can decode lazy values using LazyState:

MetaBlob 🔒

MetaDecoder 🔒

Type Aliases

CrateNumMap 🔒

A map from external crate numbers (as decoded from some crate file) to local crate numbers (as generated during this session). Each external crate may refer to types in other external crates, and each has their own crate numbers.

DeniedPartialMitigations 🔒

The set of mitigations that cannot be partially enabled (see RFC 3855), but are currently enabled for this crate.

TargetModifiers 🔒

Target modifiers - abi or exploit mitigations options that may cause unsoundness when mixed or partially enabled.
