Trait Implementations

impl Clone for SwitchCondition

fn clone(&self) -> SwitchCondition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SwitchCondition

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

Formats the value using the given formatter.

impl Display for SwitchCondition

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

impl PartialEq<SwitchCondition> for SwitchCondition

fn eq(&self, other: &SwitchCondition) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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