pub struct Daemon { /* private fields */ }

Builder for a service’s runtime. Start with daemon().

Implementations

impl Daemon

pub const DEFAULT_MAX_WORKERS: usize = 4

Upper bound on the default worker count.

pub const DEFAULT_MAX_BLOCKING: usize = pool::DAEMON_BLOCKING_THREADS

Default bound on the blocking pool.

pub fn workers(self, workers: usize) -> Daemon

Use exactly workers async worker threads (at least one).

pub fn max_blocking(self, threads: usize) -> Daemon

Bound the blocking pool at threads (at least one).

pub fn build(&self) -> Result<Runtime, Error>

Build the runtime.

Errors

pub fn run<F>(&self, main: F) -> Result<<F as Future>::Output, Error>
