Info about a parsing session.
Fields
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 AttrId
s. Every AttrId
is unique.

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
