impl Debug for ServerSessionMemoryCache

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

fn put(&self, key: Vec<u8>, value: Vec<u8>) -> bool

Store session secrets encoded in value against key, overwrites any existing value against key. Returns true if the value was stored.

fn get(&self, key: &[u8]) -> Option<Vec<u8>>

Find a value with the given key. Return it, or None if it doesn’t exist.

fn take(&self, key: &[u8]) -> Option<Vec<u8>>

Find a value with the given key. Return it and delete it; or None if it doesn’t exist.
