Fields
span_diagnostic: Handlerunstable_features: UnstableFeaturesconfig: CrateConfigedition: Editionmissing_fragment_specifiers: Lock<FxHashMap<Span, NodeId>>raw_identifier_spans: Lock<Vec<Span>>Expand description
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>>Expand description
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>Expand description
The parser has reached Eof due to an unclosed brace. Used to silence unnecessary errors.
env_depinfo: Lock<FxHashSet<(Symbol, Option<Symbol>)>>Expand description
Environment variables accessed during the build and their values when they exist.
type_ascription_path_suggestions: Lock<FxHashSet<Span>>Expand description
All the type ascriptions expressions that have had a suggestion for likely path typo.
assume_incomplete_release: boolExpand description
Whether cfg(version) should treat the current release as incomplete

pub fn expr_parentheses_needed(
&self,
err: &mut DiagnosticBuilder<'_>,

alt_snippet: Option<String>
)[src]Extend an error with a suggestion to wrap an expression with parentheses to allow the parser to continue parsing the following operation as part of the same expression.
