Struct ClientSessionMemoryCache 

pub struct ClientSessionMemoryCache { /* private fields */ }

An implementer of ClientSessionStore that stores everything in memory.

It enforces a limit on the number of entries to bound memory usage.

Implementations

impl ClientSessionMemoryCache

pub fn new(size: usize) -> Self

Make a new ClientSessionMemoryCache.

size determines the maximum number of servers to remember: size divided by MAX_TLS13_TICKETS_PER_SERVER (8), rounded up. Each server keeps up to 8 TLS 1.3 tickets. When the maximum is reached, the server that was added first is evicted.

For example, new(100) remembers up to 13 servers. Any size from 1 to 8 remembers one server, and a size of 0 remembers none.

Trait Implementations

impl ClientSessionStore for ClientSessionMemoryCache

fn set_kx_hint(&self, server_name: ServerName<'static>, group: NamedGroup)

Remember what NamedGroup the given server chose.

fn kx_hint(&self, server_name: &ServerName<'_>) -> Option<NamedGroup>

This should return the value most recently passed to set_kx_hint for the given server_name.

fn set_tls12_session( &self, _server_name: ServerName<'static>, _value: Tls12ClientSessionValue, )

Remember a TLS1.2 session.

fn tls12_session( &self, _server_name: &ServerName<'_>, ) -> Option<Tls12ClientSessionValue>

Get the most recently saved TLS1.2 session for server_name provided to set_tls12_session.

fn remove_tls12_session(&self, _server_name: &ServerName<'static>)

Remove and forget any saved TLS1.2 session for server_name.

fn insert_tls13_ticket( &self, server_name: ServerName<'static>, value: Tls13ClientSessionValue, )

Remember a TLS1.3 ticket that might be retrieved later from take_tls13_ticket, allowing resumption of this session.

fn take_tls13_ticket( &self, server_name: &ServerName<'static>, ) -> Option<Tls13ClientSessionValue>

Return a TLS1.3 ticket previously provided to add_tls13_ticket.

impl Debug for ClientSessionMemoryCache

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

Formats the value using the given formatter.
