Struct NativeH3SessionCache 

pub struct NativeH3SessionCache { /* private fields */ }

Thread-safe in-memory store of native H3 TLS session tickets.

Implementations

impl NativeH3SessionCache

pub fn new() -> Self

pub fn with_capacity(max_entries: usize, default_lifetime: Duration) -> Self

pub fn insert( &self, key: NativeH3SessionCacheKey, der: impl Into<Bytes>, max_early_data: u32, lifetime: Option<Duration>, )

Insert (or overwrite) a session ticket. lifetime of None falls back to the cache-level default. The provided max_early_data must come from the captured SSL_SESSION (e.g. via SslSessionRef::max_early_data or the legacy SSL_SESSION_get_max_early_data FFI). Pass 0 to record a ticket that the server did not authorize for 0-RTT.

pub fn get(&self, key: &NativeH3SessionCacheKey) -> Option<NativeH3SessionEntry>

Look up a session ticket. Expired tickets are removed from the cache as a side effect so subsequent calls do not return them.

pub fn evict(&self, key: &NativeH3SessionCacheKey)

Remove a single entry without consulting it.

pub fn purge_expired(&self)

Drop all expired entries.

pub fn clear(&self)

Drop every entry (e.g. when a TLS configuration change invalidates the cache).

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
