hi: BytePos

Implementations

impl<'t> Cursor<'t>

pub(crate) fn new(stream: &'t TokenStream, offset: BytePos) -> Self

pub fn at(&mut self, pos: usize) -> (BytePos, Token, BytePos)

pub fn debug(&mut self, size: usize) -> String

pub fn advance(&mut self)

pub fn advance_by(&mut self, n: usize)

pub fn lo(&self) -> BytePos

Returns the starting byte position of the next token

pub fn hi(&self) -> BytePos

Returns the highest byte position the cursor has yielded. You could also think of this as the ending position of the last yielded token.

fn map_token(&mut self, token: &Token)

fn fetch_tokens(&mut self) -> bool
