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>

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

Returns the next token. EFFECT: advances the string_reader.

pub fn peek_delimited(&self, from_ch: char, to_ch: char) -> Option<String>

Immutably extract string if found at current position with given delimiters

pub fn real_token(&mut self) -> TokenAndSpan

pub fn emit_fatal_errors(&mut self)

pub fn buffer_fatal_errors(&mut self) -> Vec<Diagnostic>

pub fn peek(&self) -> TokenAndSpan

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

pub fn new_or_buffered_errs(
    sess: &'a ParseSess,
    source_file: Lrc<SourceFile>,
    override_span: Option<Span>
) -> Result<Self, Vec<Diagnostic>>

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