Trait OverflowingSub 

pub trait OverflowingSub<Rhs = Self>: Sized {
    type Output;

    // Required method
    fn overflowing_sub(self, v: Rhs) -> (Self::Output, bool);
}

Performs substraction with a flag for overflow.

Required Associated Types

type Output

Required Methods

fn overflowing_sub(self, v: Rhs) -> (Self::Output, bool)

Returns a tuple of the difference along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.

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.
