Feeds this value into the given Hasher. Read more
source§

impl PartialEq for dyn EncodingCompressor + '_

source§

fn eq(&self, other: &Self) -> bool

1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
