Trait SafeSub 

pub trait SafeSub: Sized {
    // Required method
    fn safe_sub(self, rhs: Self) -> Result<Self, MathError>;
}

Same as checked_sub functions but returns an error

Required Methods

fn safe_sub(self, rhs: Self) -> Result<Self, MathError>

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.
