pub trait CtCheckedSub: Sized {
    // Required method
    fn ct_checked_sub(&self, v: &Self) -> CtOption<Self>;
}

Available on crate feature ct only.

Constant-time checked subtraction (the masked counterpart of CheckedSub).

Required Methods

fn ct_checked_sub(&self, v: &Self) -> CtOption<Self>

Computes self - v, returning a CtOption that is None-masked on overflow.

This trait is not dyn compatible.

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