Struct KeyComparator

pub struct KeyComparator;

Expand description

A comparator for comparing crate::key::FullKey and crate::key::UserKey with possibly different table key types.

Implementations§

impl KeyComparator

Used to compare UserKey and its encoded format.

pub fn encoded_less_than_unencoded( encoded: impl AsRef<[u8]>, unencoded: &UserKey<impl AsRef<[u8]>>, ) -> bool
