Trait constriction::backends::BoundedReadWords

pub trait BoundedReadWords<Word, S: Semantics>: ReadWords<Word, S> {
    fn remaining(&self) -> usize;

    fn is_exhausted(&self) -> bool { ... }
}

A trait for data sources that know how much data is left.

Required methods

fn remaining(&self) -> usize

Returns the number of Words that are left for reading.

If remaining() returns n then the next n calls to read must not return Ok(None), and any subsequent reads must not return Ok(Some(_)).

Provided methods

fn is_exhausted(&self) -> bool

Whether or not there is no data left to read.

You’ll usually want to overwrite the default implementation of ReadWords::maybe_exhausted to call is_exhausted, although the only strict requirement is that maybe_exhausted must not return false if is_exhausted returns true.
