# Enum stable_mir::mir::PointerCoercion

source ·

    pub enum PointerCoercion {
        ReifyFnPointer,
        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 fat pointer. This will do things like convert thin pointers to fat pointers, or convert structs containing thin pointers to structs containing fat pointers, or convert between fat pointers.

## Trait Implementations§

### impl Clone for PointerCoercion

source§

#### fn clone(&self) -> PointerCoercion

Returns a copy of the value. Read more
1.0.0 · source§

#### fn clone_from(&mut self, source: &Self)

Performs copy-assignment from `source`. Read more
source§

### impl Debug for PointerCoercion

source§

### impl PartialEq for PointerCoercion

source§

#### fn eq(&self, other: &PointerCoercion) -> bool

This method tests for `self` and `other` values to be equal, and is used by `==`.
1.0.0 · source§

#### fn ne(&self, other: &Rhs) -> bool

This method tests for `!=`. The default implementation is almost always sufficient, and should not be overridden without very good reason.

## 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.
