Trait ttk91::parsing::SeekStream

pub trait SeekStream: Iterator {
    fn offset(&self) -> usize;
    fn seek(&mut self, amount: isize);
    fn seek_boundary(&self) -> Range<isize>;
    fn at_offset(&self, offset: isize) -> Option<&Self::Item>;
}

A stream that supports seeking.

Required methods

fn offset(&self) -> usize

Returns the distance from the start of the stream to the current cursor position.

fn seek(&mut self, amount: isize)

Moves the cursor position in the stream by amount items.

fn seek_boundary(&self) -> Range<isize>

Returns the range in which the stream's cursor can move safely.

fn at_offset(&self, offset: isize) -> Option<&Self::Item>

Returns a reference to the item at the defined offset from the stream's start, if such offset exists in the stream.
