Trait FunctionPointer 

pub trait FunctionPointer:
    Primitive
    + Copy
    + Sized {
    type Args: Tuple;
    type Return;

    // Required methods
    fn call(self, args: Self::Args) -> Self::Return;
    fn cast_ptr<T: Sized, P: Pointer<T>>(self) -> P;
    fn cast_int<T: Integer>(self) -> T;
}

Required Associated Types

type Args: Tuple

type Return

Required Methods

fn call(self, args: Self::Args) -> Self::Return

fn cast_ptr<T: Sized, P: Pointer<T>>(self) -> P

fn cast_int<T: Integer>(self) -> T

Dyn Compatibility

This trait is not dyn compatible.

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

Implementations on Foreign Types
