Implementations

impl<T> Hash<T>where T: Tag,

pub fn forward_hex(&self) -> impl LowerHex + UpperHex

Displays hex forwards, regardless of how this type would display it naturally.

This is mainly intended as an internal method and you shouldn’t need it unless you’re doing something special.

pub fn backward_hex(&self) -> impl LowerHex + UpperHex

Displays hex backwards, regardless of how this type would display it naturally.

This is mainly intended as an internal method and you shouldn’t need it unless you’re doing something special.
