Trait FastInvSqrt

pub trait FastInvSqrt {
    // Required method
    fn fast_invsqrt(x: Self) -> Self;
}

Implement the fast approximate computation of ‘1/sqrt(x)’ for a type.

Required Methods

fn fast_invsqrt(x: Self) -> Self

Fast approximate computation of 1/sqrt(x).

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.
