## JobRef

# Struct JobRef

Source

    pub(crate) struct JobRef {
        pointer: *const (),
        execute_fn: unsafe fn(*const ()),
    }

Expand description

Effectively a Job trait object. Each JobRef must be executed exactly once, or else data may leak.

Internally, we store the job’s data in a `*const ()` pointer. The true type is something like `*const StackJob<...>`, but we hide it. We also carry the “execute fn” from the `Job` trait.

## Fields§

§`pointer: *const ()`§`execute_fn: unsafe fn(*const ())`

## Implementations§

Source§

### impl JobRef

Source

#### pub(crate) unsafe fn new<T>(data: *const T) -> JobRef
where T: Job,

Unsafe: caller asserts that `data` will remain valid until the job is executed.

Source

#### pub(crate) fn id(&self) -> JobRefId

Source

#### pub(crate) unsafe fn execute(self)

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
