Struct ServerHandle 

pub struct ServerHandle { /* private fields */ }

A handle to a server started by one of the Server::run* methods.

Dropping this handle without calling shutdown() leaves the server running in the background for the life of the process. Call shutdown() to stop accepting new connections and wait for already-accepted connections to finish before returning.

Implementations

impl ServerHandle

pub async fn shutdown(self)

Stop accepting new connections and wait up to DEFAULT_SHUTDOWN_DRAIN_TIMEOUT (5s) for in-flight connections to finish on their own. Equivalent to shutdown_with_timeout(DEFAULT_SHUTDOWN_DRAIN_TIMEOUT) — see that method for what happens to connections still open once the grace period elapses.

pub async fn shutdown_with_timeout(self, drain_timeout: Duration)

Stop accepting new connections and wait up to drain_timeout for in-flight connections to finish on their own.

Connections still open once drain_timeout elapses are aborted rather than waited on further: dropping the accept task drops its JoinSet, which aborts every task still tracked in it (see tokio::task::JoinSet’s own drop behavior) — which in turn drops each connection’s socket, closing it. This is what bounds shutdown when a connection has no natural end of its own (the live-reload SSE stream is the motivating case: it stays open until a watched file changes, which may never happen before the process needs to exit).
