Expand description
Trait for values and Option
s overflowing addition.
Implementing this trait leads to the following auto-implementations:
OptionOverflowingAdd<Option<InnerRhs>>
forT
.OptionOverflowingAdd<Rhs>
forOption<T>
.OptionOverflowingAdd<Option<InnerRhs>>
forOption<T>
.- … and some variants with references.
Note that since the std
library doesn’t define any
OverflowingAdd
trait,
users must provide the base implementation for the inner type.
