pub struct ServerSessionMemoryCache { /* private fields */ }
Expand description

An implementer of StoresServerSessions that stores everything in memory. If enforces a limit on the number of stored sessions to bound memory usage.

Implementations§

source§

impl ServerSessionMemoryCache

source

pub fn new(size: usize) -> Arc<Self>

Make a new ServerSessionMemoryCache. size is the maximum number of stored sessions, and may be rounded-up for efficiency.

Trait Implementations§

source§

impl StoresServerSessions for ServerSessionMemoryCache

source§

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.
source§

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

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

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.
source§

fn can_cache(&self) -> bool

Whether the store can cache another session. This is used to indicate to clients whether their session can be resumed; the implementation is not required to remember a session even if it returns true here.
