pub trait OverflowingSub: Sized + Sub<Self, Output = Self> {
// Required method
fn overflowing_sub(&self, v: &Self) -> (Self, bool);
}Expand description
Performs substraction with a flag for overflow.
Required Methods§
Sourcefn overflowing_sub(&self, v: &Self) -> (Self, bool)
fn overflowing_sub(&self, v: &Self) -> (Self, 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.
