Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

reuse_port: bool

Whether to enable reuse_port.

reuse_addr: bool

Whether to enable reuse_addr.

backlog: i32

Backlog size.

send_buf_size: Option<usize>

Send buffer size or None to use default.

recv_buf_size: Option<usize>

Recv buffer size or None to use default.

tcp_fast_open: bool

TCP fast open.

Implementations

impl ListenerOpts

pub const fn new() -> Self

Create a default ListenerOpts.

pub fn reuse_port(self, reuse_port: bool) -> Self

Enable SO_REUSEPORT

pub fn reuse_addr(self, reuse_addr: bool) -> Self

Enable SO_REUSEADDR

pub fn backlog(self, backlog: i32) -> Self

Specify backlog

pub fn send_buf_size(self, send_buf_size: usize) -> Self

Specify SO_SNDBUF

pub fn recv_buf_size(self, recv_buf_size: usize) -> Self

Specify SO_RCVBUF

pub fn tcp_fast_open(self, fast_open: bool) -> Self

Specify FastOpen. Note: if it is enabled, the connection will be established on first peer data sent, which means data cannot be sent immediately after connection accepted if client does not send something.

Trait Implementations

impl Clone for ListenerOpts

fn clone(&self) -> ListenerOpts

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ListenerOpts

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

Formats the value using the given formatter.

impl Default for ListenerOpts

fn default() -> Self

Returns the “default value” for a type.

impl Copy for ListenerOpts
