Struct ParseBuffer

pub struct ParseBuffer<'a> { /* private fields */ }

A low-level buffer of tokens which represents a completely lexed file.

A ParseBuffer will immediately lex an entire file and then store all tokens internally. A ParseBuffer only used to pass to the top-level parse function.

Implementations

impl ParseBuffer<'_>

pub fn new(input: &str) -> Result<ParseBuffer<'_>>

Creates a new ParseBuffer by lexing the given input completely.

Errors

Returns an error if input fails to lex.

pub fn new_with_lexer(lexer: Lexer<'_>) -> Result<ParseBuffer<'_>>

Creates a new ParseBuffer by lexing the given input completely.

Errors

Returns an error if input fails to lex.

pub fn track_instr_spans(&mut self, track: bool) -> &mut Self

Indicates whether the Expression::instr_spans field will be filled in.

This is useful when enabling DWARF debugging information via EncodeOptions::dwarf, for example.
