Struct Server

pub struct Server { /* private fields */ }

Implementations

impl Server

pub fn new(addr: &str) -> Result<Self>

Initialize a new default Server to run on addr

pub fn tcp_nodelay(&mut self, no_delay: bool) -> &mut Self

Configure tcp_nodelay setting for each server socket. Default: false

From mio::net::TcpStream docs:

Sets the value of the TCP_NODELAY option on this socket. If set, this option disables the Nagle algorithm. This means that segments are always sent as soon as possible, even if there is only a small amount of data. When not set, data is buffered until there is a sufficient amount to send out, thereby avoiding the frequent sending of small packets.

Note: tcp_nodelay(true) will significantly improve performance for benchmarking loads, but may not be necessary for real world usage. For example on my laptop, wrk -t2 -c100 increases from 2.5k to 92k req/s.

pub fn pool_size(&mut self, pool_size: usize) -> &mut Self

Configure the size of the thread pool that’s used for executing handlers

Defaults to num_cpus * 8. If zero is specified, unlimited threads will be spawned instead of using a thread pool.

pub fn set_keepalive_secs(&mut self, keep_alive_secs: u64) -> &mut Self

Configure keep-alive timeout in seconds

Defaults to 5 seconds

pub fn start<F>(&self, func: F) -> Result<()>

where F: Send + Sync + 'static + Fn(Request) -> Response<Vec<u8>>,

Start the server using the given handler function
