Trait Implementations

impl<T1: Clone, T2: Clone> Clone for SelectTwoOutput<T1, T2>

fn clone(&self) -> SelectTwoOutput<T1, T2>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T1: Eq, T2: Eq> Eq for SelectTwoOutput<T1, T2>

impl<T1: PartialEq, T2: PartialEq> PartialEq for SelectTwoOutput<T1, T2>

fn eq(&self, other: &SelectTwoOutput<T1, T2>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
