Info about a parsing session.

Fields§

§dcx: DiagCtxt§unstable_features: UnstableFeatures§config: Cfg§check_config: CheckCfg§edition: Edition§raw_identifier_spans: AppendOnlyVec<Span>

Places where raw identifiers were used. This is used to avoid complaining about idents clashing with keywords in new editions.

§bad_unicode_identifiers: Lock<FxIndexMap<Symbol, Vec<Span>>>

Places where identifiers that contain invalid Unicode codepoints but that look like they should be. Useful to avoid bad tokenization when encountering emoji. We group them to provide a single error per unique incorrect identifier.

§source_map: Lrc<SourceMap>§buffered_lints: Lock<Vec<BufferedEarlyLint>>§ambiguous_block_expr_parse: Lock<FxIndexMap<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: GatedSpans§symbol_gallery: SymbolGallery§env_depinfo: Lock<FxIndexSet<(Symbol, Option<Symbol>)>>

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

§file_depinfo: Lock<FxIndexSet<Symbol>>

File paths accessed during the build.

§assume_incomplete_release: bool

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

§proc_macro_quoted_spans: AppendOnlyVec<Span>

Spans passed to proc_macro::quote_span. Each span has a numerical identifier represented by its position in the vector.

§attr_id_generator: AttrIdGenerator

Used to generate new AttrIds. Every AttrId is unique.
