Trait RuntimeDriver 

pub trait RuntimeDriver: Clone + 'static {
    // Required methods
    fn now(&self) -> Duration;
    fn sleep_until(&self, deadline: Duration) -> LocalBoxFuture<'static, ()>;
    fn yield_now(&self) -> LocalBoxFuture<'static, ()>;
    fn spawn_local(&self, task: LocalTask) -> Result<DriverTask, SpawnError>;
    fn shutdown_requested(&self) -> bool;

    // Provided method
    fn jitter(&self, _maximum: Duration) -> Duration { ... }
}

Host facilities required to advance the portable Kernel.

Required Methods

fn now(&self) -> Duration

Returns the current monotonic instant relative to Driver startup.

fn sleep_until(&self, deadline: Duration) -> LocalBoxFuture<'static, ()>

Waits until the supplied monotonic instant.

fn yield_now(&self) -> LocalBoxFuture<'static, ()>

Cooperatively yields to other work on the local task lane.

fn spawn_local(&self, task: LocalTask) -> Result<DriverTask, SpawnError>

Schedules Kernel-owned work on the local task lane.

fn shutdown_requested(&self) -> bool

Reports whether the embedding Runner requested shutdown.

Provided Methods

fn jitter(&self, _maximum: Duration) -> Duration

Supplies deterministic or entropy-backed jitter bounded by the policy value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
