struct TokenTreesReader<'a> {
    string_reader: StringReader<'a>,
    token: Token,
    open_braces: Vec<(Delimiter, Span)>,
    unmatched_braces: Vec<UnmatchedBrace>,

}

Fields

string_reader: StringReader<'a>

token: Token

open_braces: Vec<(Delimiter, Span)>

Stack of open delimiters and their spans. Used for error message.

unmatched_braces: Vec<UnmatchedBrace>

matching_delim_spans: Vec<(Delimiter, Span, Span)>

The type and spans for all braces

Used only for error recovery when arriving to EOF with mismatched braces.

last_unclosed_found_span: Option<Span>

last_delim_empty_block_spans: FxHashMap<Delimiter, Span>

Collect empty block spans that might have been auto-inserted by editors.

matching_block_spans: Vec<(Span, Span)>

Collect the spans of braces (Open, Close). Used only for detecting if blocks are empty and only braces.

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.
