Fields

sess: &'a ParseSess

next_pos: BytePos

The absolute offset within the codemap of the next character to read

pos: BytePos

filemap: Lrc<FileMap>

Methods

impl<'a> StringReader<'a>

pub fn real_token(&mut self) -> TokenAndSpan

pub fn try_next_token(&mut self) -> Result<TokenAndSpan, ()>

Return the next token. EFFECT: advances the string_reader.

pub fn emit_fatal_errors(&mut self)

pub fn peek(&self) -> TokenAndSpan

pub fn new(     sess: &'a ParseSess,     filemap: Lrc<FileMap>,     override_span: Option<Span> ) -> Self

pub fn retokenize(sess: &'a ParseSess, span: Span) -> Self
