Implementors

impl Reader for AccumulatingReader[src]

fn peek(&mut self, off: usize) -> Option<char>[src]

Return the value of the byte that is off bytes away from the current position in the input file. If the off lies beyond the end of file, None is returned.

fn consume(&mut self, amt: usize)[src]

Consume the next amt bytes of the input. All consumed bytes since the last clear() can be accessed via slice() or to_string().

fn clear(&mut self)[src]

Clear the consumed bytes.

fn to_string(&self) -> String[src]

Convert the consumed bytes to a String.
