Info about a parsing session.

Fields

dcx: DiagCtxt

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: Arc<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

attr_id_generator: AttrIdGenerator

Used to generate new AttrIds. Every AttrId is unique.

Layout

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.
