Enum ExecutorKind 

pub enum ExecutorKind {
    Naive,
    GpuReactor,
    IoUring,
}

How a waiting thread runs a wait.

Variants

Naive

The wait runs inline on the waiting thread: a blocking sleep, then a blocking park or poll. Other work proceeds only on other threads or through issue-ahead.

GpuReactor

The wait is a task of this crate’s Executor: its idle sleeps to the earliest predicted deadline, then parks on the completion line; ready tasks run between.

IoUring

As GpuReactor, with the deadline sleep an IORING_OP_TIMEOUT (ns) on an io_uring.

Implementations

impl ExecutorKind

pub const ALL: [ExecutorKind; 3]

Every kind, in declared order.

pub fn parse(text: &str) -> Result<Self>

Parse a spelling (naive, gpu-reactor, io-uring).

Errors

InvalidExecutor.

Trait Implementations

impl Clone for ExecutorKind

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ExecutorKind

impl Declared for ExecutorKind

const FALLBACK_CODE: ErrorCode = ErrorCode::ExecutorFallback

The code of the warning a fallback emits: (requested, why, running).

const REFUSED_CODE: ErrorCode = ErrorCode::ExecutorRefused

The code of the refusal a strict setting emits: (requested, why).

type Caps = ExecutorCaps

What the host offers, probed once by the host (never by the core).

fn name(self) -> &'static str

The value’s spelling.

fn lacks(self, caps: &ExecutorCaps) -> Option<String>

Why self cannot run on caps, or None when it can.

fn fallback(self) -> Option<Self>

The declared fallback of self (None: the end of the chain, which must run anywhere).
