Struct HeapJob

Source 
pub(crate) struct HeapJob<BODY>
where
    BODY: FnOnce(JobRefId) + Send,
{
    job: BODY,
    tlv: Tlv,
}
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.)

Implementations§

Source§

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

Source

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

Source

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.

Source

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

Creates a static JobRef from this job.

Trait Implementations§

Source§

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

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.

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.
