Trait option_operations::div::OptionDiv

pub trait OptionDiv<Rhs, InnerRhs = Rhs> {
    type Output;
    fn opt_div(self, rhs: Rhs) -> Option<Self::Output>;
}

Trait for values and Options division.

Implementing this type leads to the following auto-implementations:

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

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

Associated Types

type Output

The resulting inner type after applying the operation.

Required methods

fn opt_div(self, rhs: Rhs) -> Option<Self::Output>

Computes the division.

Returns None if at least one argument is None.

Panics

Most implementations will panic if rhs is 0.
