Trait OptionDiv 

pub trait OptionDiv<Rhs = Self, InnerRhs = Rhs> {
    type Output;

    // Required method
    fn opt_div(self, rhs: Rhs) -> Option<Self::Output>;
}
Expand description

Trait for values and Options division.

Implementing this trait 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>.

Required Associated Types§

type Output

The resulting inner type after applying the division.

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 zero.

Dyn Compatibility§

This trait is dyn compatible.

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