Trait FunctionPointer

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

    // Required method
    fn call(self, args: Self::Args) -> Self::Return;
}

Required Associated Types

type Args: Tuple

type Return

Required Methods

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

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.

Implementations on Foreign Types

impl<A1, R> FunctionPointer for fn(A1₁, A1₂, …, A1ₙ) -> R

This trait is implemented for function pointers with up to 12 arguments.

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

impl<R> FunctionPointer for fn() -> R

type Args = ()

type Return = R

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