Struct Parser 

pub struct Parser<'eng, 'tokens> {
    pub tokens: Vec<Token<'tokens>>,
    pub meta: Arc<SourceMeta>,
    pub pos: usize,
    pub diag_engine: &'eng mut DiagnosticEngine<Code>,
}

Token-stream cursor + diagnostic engine. 'tokens ties borrowed lexemes to the source; 'eng ties the engine borrow to the caller.

Fields

tokens: Vec<Token<'tokens>>

meta: Arc<SourceMeta>

pos: usize

diag_engine: &'eng mut DiagnosticEngine<Code>

Implementations

impl<'eng, 'tokens> Parser<'eng, 'tokens>

pub fn new( tokens: Vec<Token<'tokens>>, meta: Arc<SourceMeta>, diag_engine: &'eng mut DiagnosticEngine<Code>, ) -> Self

Build a parser positioned at the first token.

pub fn parse(&mut self) -> Document

Drive the top-level loop until EOF. Force-advances on no-progress so a malformed token cannot wedge the parser.
