## ArcJob

# Struct ArcJob

    pub(crate) struct ArcJob<BODY>where
        BODY: Fn(JobRefId) + Send + Sync,{
        job: BODY,
    }

Expand description

Represents a job stored in an `Arc` – like `HeapJob`, but may be turned into multiple `JobRef`s and called multiple times.

## Fields§

§`job: BODY`

## Implementations§

Source§

### impl<BODY> ArcJob<BODY>
where BODY: Fn(JobRefId) + Send + Sync,

Source

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

Source

#### pub(crate) unsafe fn as_job_ref(this: &Arc<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.

Source

#### pub(crate) fn as_static_job_ref(this: &Arc<Self>) -> JobRef
where BODY: 'static,

Creates a static `JobRef` from this job.

## Trait Implementations§

Source§

### impl<BODY> Job for ArcJob<BODY>
where BODY: Fn(JobRefId) + Send + Sync,

Source§

#### 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.

## Auto Trait Implementations§

## Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
