Struct crossbeam_epoch::deferred::Deferred

pub(crate) struct Deferred {
    call: unsafe fn(_: *mut u8),
    data: MaybeUninit<[usize; 3]>,
    _marker: PhantomData<*mut ()>,
}

A FnOnce() that is stored inline if small, or otherwise boxed on the heap.

This is a handy way of keeping an unsized FnOnce() within a sized structure.

Fields

call: unsafe fn(_: *mut u8)

data: MaybeUninit<[usize; 3]>

_marker: PhantomData<*mut ()>
