Trait CheckedPow 

pub trait CheckedPow: Sized + Mul<Self> {
    // Required method
    fn checked_pow(self, exp: u32) -> Option<<Self as Mul<Self>>::Output>;
}

Performs exponentiation, returning None if overflow occurred.

Required Methods

fn checked_pow(self, exp: u32) -> Option<<Self as Mul<Self>>::Output>

Checked exponentiation. Computes self.pow(exp), returning None if overflow occurred.

Note that 0⁰ returns Some(1), matching the inherent checked_pow on the primitive integer types.

Examples

use const_num_traits::CheckedPow;

assert_eq!(CheckedPow::checked_pow(2i8, 4), Some(16));
assert_eq!(CheckedPow::checked_pow(7i8, 8), None);
assert_eq!(CheckedPow::checked_pow(0u32, 0), Some(1));

Dyn Compatibility

This trait is not dyn compatible.

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