Enum PointerCoercion

Source

pub enum PointerCoercion {

    UnsafeFnPointer,
    ClosureFnPointer(Safety),
    MutToConstPointer,
    ArrayToPointer,
    Unsize,
}

Variants§

§

ReifyFnPointer

Go from a fn-item type to a fn-pointer type.

§

UnsafeFnPointer

Go from a safe fn pointer to an unsafe fn pointer.

§

ClosureFnPointer(Safety)

Go from a non-capturing closure to a fn pointer or an unsafe fn pointer. It cannot convert a closure that requires unsafe.

§

MutToConstPointer

Go from a mut raw pointer to a const raw pointer.

§

ArrayToPointer

Go from *const [T; N] to *const T

§

Unsize

Unsize a pointer/reference value, e.g., &[T; n] to &[T]. Note that the source could be a thin or wide pointer. This will do things like convert thin pointers to wide pointers, or convert structs containing thin pointers to structs containing wide pointers, or convert between wide pointers.
