Trait CheckedAdd 

pub trait CheckedAdd: Sized {
    type Output;

    // Required method
    fn checked_add(self, v: Self) -> Option<Self::Output>;
}

Performs addition, returning None if overflow occurred.

Required Associated Types

type Output

The result type. Self for the primitive impls; a distinct owned type lets non-Copy types implement this via impl for &Self.

Required Methods

fn checked_add(self, v: Self) -> Option<Self::Output>

Adds two numbers, checking for overflow. If overflow happens, None is returned.

Dyn Compatibility

This trait is not dyn compatible.

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