source§

impl Hash for StashKey

source§

1.3.0 · source§

fn hash_slice<H>(data: &[Self], state: &mut H)

source§

impl PartialEq for StashKey

source§

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

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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

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