IdleTimeout

rama::http::core::server::conn

Struct IdleTimeout 

pub struct IdleTimeout {
    pub first_request: Duration,
    pub idle: Duration,
}
Available on crate features http-backend and http and std only.
Expand description

Budget for a connection without open requests before it is closed.

A connection is idle while it has no open request, no request head in progress and no tunnel; a WebSocket, a CONNECT tunnel or a streamed response keeps its request open. A connection that never received a complete request head gets one first_request window, counted from when it first went idle: requests and heads in progress pause it but never restart it. Once a complete head arrived, the connection earns the full idle budget after every request.

HTTP/1 closes the connection; HTTP/2 and HTTP/3 send a graceful GOAWAY and close once requests that raced it are done.

Fields§

§first_request: Duration

Window for a connection that has not received a complete request head yet.

Extended by four round trips, at most doubled, when the connection measured its round-trip time.

§idle: Duration

Budget for a connection that received a complete request head.

Implementations§

§

impl IdleTimeout

pub const DEFAULT: IdleTimeout

10 s for the first request and 30 s once a request was received.

Established browsers discard preconnected sockets they did not use within about ten seconds, and 30 s keeps a connection for the next navigation or API poll without hoarding sockets.
