Struct lrlex::LRNonStreamingLexer

pub struct LRNonStreamingLexer<'lexer, 'input: 'lexer, StorageT> { /* fields omitted */ }

An LRNonStreamingLexer holds a reference to a string and can lex it into lrpar::Lexemes. Although the struct is tied to a single string, no guarantees are made about whether the lexemes are cached or not.

Trait Implementations

impl<'lexer, 'input: 'lexer, StorageT: Copy + Eq + Hash + PrimInt + Unsigned> Lexer<StorageT> for LRNonStreamingLexer<'lexer, 'input, StorageT>

fn iter<'a>(
    &'a self
) -> Box<dyn Iterator<Item = Result<Lexeme<StorageT>, LexError>> + 'a>

Iterate over all the lexemes in this lexer. Note that: * The lexer may or may not stop after the first [LexError] is encountered. * There are no guarantees about what happens if this function is called more than once. For example, a streaming lexer may only produce [Lexeme]s on the first call.

fn span_str(&self, span: Span) -> &'input str

Return the user input associated with a [Span].

fn span_lines_str(&self, span: Span) -> &'input str

Return the lines containing the input at span (including all the text on the lines that span starts and ends on).

fn line_col(&self, span: Span) -> ((usize, usize), (usize, usize))

Return ((start line, start column), (end line, end column)) for span. Note that column characters (not bytes) are returned.
