Struct KeepAlive 

pub struct KeepAlive {
    pub interval: Duration,
    pub timeout: Duration,
    pub close: CloseFrame,
}

Server-initiated keepalive: send a Ping when the connection goes idle, and disconnect the peer if it doesn’t respond in time.

This is the proactive half of ping/pong — wslay already auto-answers incoming pings, but never initiates its own. Browsers can’t send pings from JavaScript, so liveness for an h2ts client must be driven from the server; the browser’s platform auto-answers these pings transparently.

Fields

interval: Duration

Send a Ping once the connection has been idle (no frame received) this long.

timeout: Duration

If no frame arrives within this long after that Ping, close the peer.

close: CloseFrame

Close frame sent to the peer, and surfaced to BridgeConfig::on_close, when keepalive fails. Defaults to 1001 (Going Away), “keepalive timeout”.

Implementations

impl KeepAlive

pub fn new(interval: Duration, timeout: Duration) -> Self

Keepalive with the given ping interval and response timeout, closing with 1001 (Going Away) on failure.

Trait Implementations

impl Clone for KeepAlive

fn clone(&self) -> KeepAlive

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KeepAlive

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

Formats the value using the given formatter.

impl Default for KeepAlive

fn default() -> Self

Sensible server defaults: ping an idle connection every 30s and close it (1001 Going Away) if no frame arrives within a further 15s. This is what BridgeConfig::default (and thus bridge / serve_h2) use — keepalive is on by default. Tune via KeepAlive::new, or set BridgeConfig::keepalive to None to opt out.
