Trait num::CheckedAdd
[−]
[src]
pub trait CheckedAdd: Add<Self, Output = Self> {
fn checked_add(&self, v: &Self) -> Option<Self>;
}Performs addition that returns None instead of wrapping around on
overflow.
Required Methods
fn checked_add(&self, v: &Self) -> Option<Self>
Adds two numbers, checking for overflow. If overflow happens, None is
returned.
