Struct TcpOptions 

#[non_exhaustive]
pub struct TcpOptions {
    pub nodelay: Option<bool>,
    pub keepalive: Option<Keepalive>,
    pub linger: Option<Linger>,
    pub send_buffer: Option<u32>,
    pub receive_buffer: Option<u32>,
    pub ttl: Option<u8>,
}

Options applied to each accepted or dialed TCP connection. None leaves the OS default.

use net_io::{Keepalive, TcpOptions};
let opts = TcpOptions::new().nodelay(true).keepalive(Keepalive::DEFAULT);
assert_eq!(opts.nodelay, Some(true));

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.

nodelay: Option<bool>

TCP_NODELAY.

keepalive: Option<Keepalive>

Keepalive probes.

linger: Option<Linger>

Linger at close.

send_buffer: Option<u32>

SO_SNDBUF.

receive_buffer: Option<u32>

SO_RCVBUF.

ttl: Option<u8>

Hop limit (IP_TTL / IPV6_UNICAST_HOPS).
