pub enum KeepAlive {
    Timeout(Duration),
    Os,
    Disabled,
}
Expand description

Connection keep-alive config.

Variants§

§

Timeout(Duration)

Keep-alive duration.

KeepAlive::Timeout(Duration::ZERO) is mapped to KeepAlive::Disabled.

§

Os

Rely on OS to shutdown TCP connection.

Some defaults can be very long, check your OS documentation.

§

Disabled

Keep-alive is disabled.

Connections will be closed immediately.
