Info about a parsing session.


§span_diagnostic: Handler§unstable_features: UnstableFeatures§config: CrateConfig§check_config: CrateCheckConfig§edition: Edition§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: 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.

§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.

§attr_id_generator: AttrIdGenerator

Used to generate new AttrIds. Every AttrId is unique.


Used for testing.

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.
