Trait SafeFnPtr 

pub trait SafeFnPtr: FnPtr<Safety = Safe> {
    // Required method
    fn invoke(&self, args: Self::Args) -> Self::Output;
}

Marker trait for all callable safe function pointer types (fn / extern fn).

Required Methods

fn invoke(&self, args: Self::Args) -> Self::Output

Invokes the function pointed to with the given args.

Examples

fn add(a: i32, b: i32) -> i32 { a + b }

let f: fn(i32, i32) -> i32 = add;
let result = f.invoke((2, 3));
assert_eq!(result, 5);

Dyn Compatibility

This trait is not dyn compatible.

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