Trait CheckedIsqrt 

pub trait CheckedIsqrt: Sized {
    type Output;

    // Required method
    fn checked_isqrt(self) -> Option<Self::Output>;
}

Integer square root of signed values, None for negative inputs.

Required Associated Types

type Output

Returns the integer square root, or None if self is negative. Like std, this is only provided for signed types.

use const_num_traits::CheckedIsqrt;

assert_eq!(CheckedIsqrt::checked_isqrt(10i32), Some(3));
assert_eq!(CheckedIsqrt::checked_isqrt(-1i32), None);

Required Methods

fn checked_isqrt(self) -> Option<Self::Output>

Dyn Compatibility

This trait is not dyn compatible.

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