Marker trait for all function pointers.

Required Associated Constants

const ARITY: usize

The function’s arity (number of arguments).

const IS_SAFE: bool

Whether the function pointer is safe (fn) or unsafe (unsafe fn).

const IS_EXTERN: bool

Whether the function pointer uses an extern calling convention.

const ABI: Abi

The ABI associated with this function pointer.

Required Associated Types

type Args

The argument types as a tuple.

type Output

The return type.

type ArityMarker: Arity

Marker type denoting arity

type SafetyMarker: Safety

Marker type denoting safety

type AbiMarker: Abi

Marker type denoting abi

Required Methods

fn as_ptr(&self) -> UntypedFnPtr

Returns a untyped function pointer for this function.

unsafe fn from_ptr(ptr: UntypedFnPtr) -> Self

Constructs an instance from an untyped function pointer.

Safety

The given pointer has to point to a function of the correct type.

Provided Methods

fn addr(&self) -> usize

Returns the address of this function.

unsafe fn from_addr(addr: usize) -> Self

Constructs an instance from an address.

Safety

The given pointer has to point to a function of the correct type.

fn as_unsafe(&self) -> <Self as WithSafety<Unsafe>>::F

where Self: AsUnsafe,

Produces an unsafe version of this function pointer.

unsafe fn as_safe(&self) -> <Self as WithSafety<Safe>>::F

where Self: AsSafe,

Produces a safe version of this function pointer.

Safety

Caller must ensure the underlying function is actually safe to call.

unsafe fn with_abi<Abi: Abi>(&self) -> <Self as WithAbi<Abi>>::F

where Self: WithAbi<Abi>,

Produces a version of this function pointer with the given ABI.

Safety

Caller must ensure that the resulting ABI transformation is sound.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
