Trait CtCheckedSignedDiff 

pub trait CtCheckedSignedDiff: Sized {
    type Signed;

    // Required method
    fn ct_checked_signed_diff(&self, rhs: &Self) -> CtOption<Self::Signed>;
}

Available on crate feature ct only.

Constant-time signed difference of unsigned values (the masked counterpart of CheckedSignedDiff).

Required Associated Types

type Signed

The signed counterpart type.

Required Methods

fn ct_checked_signed_diff(&self, rhs: &Self) -> CtOption<Self::Signed>

Computes self - rhs as a signed value, None-masked if it doesn’t fit.

Dyn Compatibility

This trait is not dyn compatible.

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