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 to avoid complaining about idents clashing with keywords in new editions.

bad_unicode_identifiers: Lock<FxHashMap<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<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.

file_depinfo: Lock<FxHashSet<Symbol>>

File paths accessed during the build.

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

proc_macro_quoted_spans: Lock<Vec<Span>>

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

Implementations

Used for testing.

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.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
