Info about a parsing session.
Fields
span_diagnostic: Handler
unstable_features: UnstableFeatures
config: CrateConfig
edition: Edition
missing_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.
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: GatedSpans
symbol_gallery: SymbolGallery
reached_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
