Trait option_operations::add::OptionAddAssign

pub trait OptionAddAssign<Rhs = Self, InnerRhs = Rhs> {
    // Required method
    fn opt_add_assign(&mut self, rhs: Rhs);
}

Trait for values and Options addition assignment.

Implementing this trait leads to the following auto-implementations:

• OptionAddAssign<Option<InnerRhs>> for T.
• OptionAddAssign<Rhs> for Option<T>.
• OptionAddAssign<Option<InnerRhs>> for Option<T>.
• … and some variants with references.

This trait is auto-implemented for OptionOperations types implementing Add<Rhs>.

Required Methods

fn opt_add_assign(&mut self, rhs: Rhs)

Performs the addition assignment.

self is unchanged if rhs is None.
