Struct RuntimeBuilder 

pub struct RuntimeBuilder { /* private fields */ }

Builder for Runtime.

Implementations

impl RuntimeBuilder

pub fn new() -> Self

Create the builder with default config.

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

Sets the number of scheduler ticks after which the scheduler will poll for external events (timers, I/O, and so on).

A scheduler “tick” roughly corresponds to one poll invocation on a task. Values below 1 are treated as 1.

pub fn self_wake_threshold( &mut self, count: u32, duration: Duration, ) -> &mut Self

Sets the self-wake streak that is reported as a possible busy loop.

A task that wakes itself on every poll, for example a loop around wake_by_ref() or a yield, never waits for an event. The runtime logs a warning with the task spawn location once the task wakes itself count times in a row and the streak lasts at least duration. Each streak is reported once. A count of 0 disables the warning and per-task streak tracking, but preserves Runtime::self_wake_count.

By default, 10 000 self-wakes over at least 1 second.

pub fn build(&self, handle: Box<dyn Notify>) -> Runtime

Build Runtime.

impl Default for RuntimeBuilder

fn default() -> Self
