Struct RuntimeBuilder 

pub struct RuntimeBuilder { /* private fields */ }

Builder for Runtime.

Implementations

impl RuntimeBuilder

pub fn new() -> Self

Creates a builder with the default scheduler budgets and warning thresholds.

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

Sets the local task-poll budget for one Runtime::poll call.

The driver can process external events between calls. Remote work is serviced in separate batches, so this is not a strict limit on all work done in one call. The default is 61; zero is treated as one.

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

Creates a native runtime using this configuration and driver notifier.

Does not start an event loop. The notifier must wake the driver used to run this runtime.

Trait Implementations

impl Clone for RuntimeBuilder

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuntimeBuilder

impl Default for RuntimeBuilder

fn default() -> Self

Uses the default scheduler budgets and self-wake thresholds.
