[−][src]Struct syntax::parse::lexer::StringReader
Fields
sess: &'a ParseSess
next_pos: BytePos
The absolute offset within the source_map of the next character to read
pos: BytePos
The absolute offset within the source_map of the current character
ch: Option<char>
The current character (which has been read from self.pos)
source_file: Lrc<SourceFile>
end_src_index: usize
Stop reading src at this index.
Methods
impl<'a> StringReader<'a>
[src]
pub fn try_next_token(&mut self) -> Result<TokenAndSpan, ()>
[src]
Returns the next token. EFFECT: advances the string_reader.
pub fn peek_delimited(&self, from_ch: char, to_ch: char) -> Option<String>
[src]
Immutably extract string if found at current position with given delimiters
pub fn real_token(&mut self) -> TokenAndSpan
[src]
pub fn emit_fatal_errors(&mut self)
[src]
pub fn buffer_fatal_errors(&mut self) -> Vec<Diagnostic>
[src]
pub fn peek(&self) -> TokenAndSpan
[src]

sess: &'a ParseSess,
source_file: Lrc<SourceFile>,
override_span: Option<Span>
