Struct socket2::TcpKeepalive

pub struct TcpKeepalive { /* private fields */ }

Configures a socket’s TCP keepalive parameters.

See Socket::set_tcp_keepalive.

Implementations

impl TcpKeepalive

pub const fn new() -> TcpKeepalive

Returns a new, empty set of TCP keepalive parameters.

pub const fn with_time(self, time: Duration) -> Self

Set the amount of time after which TCP keepalive probes will be sent on idle connections.

This will set TCP_KEEPALIVE on macOS and iOS, and TCP_KEEPIDLE on all other Unix operating systems, except OpenBSD and Haiku which don’t support any way to set this option. On Windows, this sets the value of the tcp_keepalive struct’s keepalivetime field.

Some platforms specify this value in seconds, so sub-second specifications may be omitted.

pub const fn with_interval(self, interval: Duration) -> Self

Available on Android or DragonFly BSD or FreeBSD or Fuchsia or illumos or iOS or Linux or macOS or NetBSD or tvOS or watchOS or Windows only.

Set the value of the TCP_KEEPINTVL option. On Windows, this sets the value of the tcp_keepalive struct’s keepaliveinterval field.

Sets the time interval between TCP keepalive probes.

Some platforms specify this value in seconds, so sub-second specifications may be omitted.

pub const fn with_retries(self, retries: u32) -> Self

Available on crate feature all and (Android or DragonFly BSD or FreeBSD or Fuchsia or illumos or iOS or Linux or macOS or NetBSD or tvOS or watchOS) only.

Set the value of the TCP_KEEPCNT option.

Set the maximum number of TCP keepalive probes that will be sent before dropping a connection, if TCP keepalive is enabled on this socket.
