StackJob in rustc_thread_pool::job - Rust
Description: A job that will be owned by a stack slot. This means that when it executes it need not free any heap data, the cleanup occurs when the stack frame is later popped. The function parameter indicates `true` if the job was stolen – executed on a different thread.

## StackJob

# Struct StackJob

Source

    pub(crate) struct StackJob<L, F, R>where
        L: Latch + Sync,
        F: FnOnce(bool) -> R + Send,
        R: Send,{
        pub(crate) latch: L,
        func: UnsafeCell<Option<F>>,
        result: UnsafeCell<JobResult<R>>,
        tlv: Tlv,
    }

Expand description

A job that will be owned by a stack slot. This means that when it executes it need not free any heap data, the cleanup occurs when the stack frame is later popped. The function parameter indicates `true` if the job was stolen – executed on a different thread.

## Implementations§

Source§

### impl<L, F, R> StackJob<L, F, R>
where L: Latch + Sync, F: FnOnce(bool) -> R + Send, R: Send,

Source

#### pub(crate) fn new(tlv: Tlv, func: F, latch: L) -> StackJob<L, F, R>

Source

#### pub(crate) unsafe fn as_job_ref(&self) -> JobRef

## Trait Implementations§

Source§

### impl<L, F, R> Job for StackJob<L, F, R>
where L: Latch + Sync, F: FnOnce(bool) -> R + Send, R: 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.
