Trait FnPtr 

pub trait FnPtr: Copy {
    // Required methods
    fn as_ptr(self) -> NonNull<Code>;
    unsafe fn from_ptr(ptr: NonNull<Code>) -> Self;

    // Provided method
    fn addr(self) -> usize { ... }
}

🔬This is a nightly-only experimental API. (fn_static #148768)

A common trait implemented by all function pointers.

Required Methods

fn as_ptr(self) -> NonNull<Code>

🔬This is a nightly-only experimental API. (fn_static #148768)

Returns the function pointer as a NonNull<Code>.

unsafe fn from_ptr(ptr: NonNull<Code>) -> Self

🔬This is a nightly-only experimental API. (fn_static #148768)

Constructs a function pointer from a NonNull pointer.

Safety

The function pointer must have been obtained from an FnPtr::as_ptr call from a function pointer type that is ABI compatible.

Provided Methods

fn addr(self) -> usize

🔬This is a nightly-only experimental API. (fn_static #148768)

Returns the address of the function pointer.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
