Trait AsSafe 

pub trait AsSafe: WithSafety<Safe> {
    type F: FnPtr<Args = Self::Args, Output = Self::Output, Safety = Safe, Abi = Self::Abi>;
}

Helper trait to compute the safe version of a function pointer type while preserving its abi, arguments and return type. Equivalent to WithSafety<Safe>.

Example

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

Required Associated Types

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

The safe version of this 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<Safe>> AsSafe for F

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