Fields

span_diagnostic: Handlerunstable_features: UnstableFeaturesconfig: CrateConfigedition: Editionmissing_fragment_specifiers: Lock<FxHashMap<Span, NodeId>>raw_identifier_spans: Lock<Vec<Span>>

Places where raw identifiers were used. This is used for feature-gating raw identifiers.

source_map: Lrc<SourceMap>buffered_lints: Lock<Vec<BufferedEarlyLint>>ambiguous_block_expr_parse: Lock<FxHashMap<Span, Span>>

Contains the spans of block expressions that could have been incomplete based on the operation token that followed it, but that the parser cannot identify without further analysis.

gated_spans: GatedSpanssymbol_gallery: SymbolGalleryreached_eof: Lock<bool>

The parser has reached Eof due to an unclosed brace. Used to silence unnecessary errors.

env_depinfo: Lock<FxHashSet<(Symbol, Option<Symbol>)>>

Environment variables accessed during the build and their values when they exist.

type_ascription_path_suggestions: Lock<FxHashSet<Span>>

All the type ascriptions expressions that have had a suggestion for likely path typo.

assume_incomplete_release: bool

Whether cfg(version) should treat the current release as incomplete
