type Error = ET

fn try_get( &self, key: impl Borrow<Self::Key>, ) -> Result<Option<Self::Value>, Self::Error>

Attempts to return an option of the owned cache element if present

fn try_set( &mut self, key: impl Borrow<Self::Key>, value: impl Borrow<Self::Value>, ) -> Result<(), Self::Error>

Attempts to set a value given its key.

fn try_exists(&self, key: impl Borrow<Self::Key>) -> Result<bool, Self::Error>

Attempts to check if the cache key entry exists.
