Trait AsUnsafe 

pub trait AsUnsafe<F: FnPtr>: WithSafety<Unsafe> {
    type F: FnPtr<Args = F::Args, Output = F::Output, Safety = Unsafe, Abi = F::Abi>;
}

Helper trait to compute the unsafe version of a function pointer type while preserving arity, abi and signature.

Example

type S = extern "C" fn(i32) -> i32;
type U = <S as AsUnsafe<S>>::F;
// `U` is `unsafe extern "C" fn(i32) -> i32`

Required Associated Types

type F: FnPtr<Args = F::Args, Output = F::Output, Safety = Unsafe, Abi = F::Abi>

The unsafe version of a function pointer type.

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.

Implementors

impl<F: FnPtr + WithSafety<Unsafe>> AsUnsafe<F> for F

type F = <F as WithSafety<Unsafe>>::F
