Struct rayon_core::job::JobRef

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

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

impl JobRef

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

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

pub(crate) fn id(&self) -> impl Eq

Returns an opaque handle that can be saved and compared, without making JobRef itself Copy + Eq.

pub(crate) unsafe fn execute(self)
