Struct TokenTreeDiagInfo

source 
pub(super) struct TokenTreeDiagInfo {
    pub open_braces: Vec<(Delimiter, Span)>,
    pub unmatched_delims: Vec<UnmatchedDelim>,
    pub last_unclosed_found_span: Option<Span>,
    pub empty_block_spans: Vec<Span>,
    pub matching_block_spans: Vec<(Span, Span)>,
}

Fields§

§open_braces: Vec<(Delimiter, Span)>

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

§unmatched_delims: Vec<UnmatchedDelim>§last_unclosed_found_span: Option<Span>

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

§empty_block_spans: Vec<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.
