Struct rayon_core::job::HeapJob

pub(crate) struct HeapJob<BODY>where
    BODY: FnOnce() + Send,{
    job: BODY,
}

Expand description

Represents a job stored in the heap. Used to implement scope. Unlike StackJob, when executed, HeapJob simply invokes a closure, which then triggers the appropriate logic to signal that the job executed.

(Probably StackJob should be refactored in a similar fashion.)

Fields§

§job: BODY

Implementations§

impl<BODY> HeapJob<BODY>
where BODY: FnOnce() + Send,

pub(crate) fn new(job: BODY) -> Box<Self>

pub(crate) unsafe fn into_job_ref(self: Box<Self>) -> JobRef

Creates a JobRef from this job – note that this hides all lifetimes, so it is up to you to ensure that this JobRef doesn’t outlive any data that it closes over.

pub(crate) fn into_static_job_ref(self: Box<Self>) -> JobRef
where BODY: 'static,

Creates a static JobRef from this job.

Trait Implementations§

impl<BODY> Job for HeapJob<BODY>
where BODY: FnOnce() + Send,

unsafe fn execute(this: *const ())

Unsafe: this may be called from a different thread than the one which scheduled the job, so the implementer must ensure the appropriate traits are met, whether Send, Sync, or both.
