Trait Implementations

impl Clone for OptionSelectionState

fn clone(&self) -> OptionSelectionState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionSelectionState

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

Formats the value using the given formatter.

impl Default for OptionSelectionState

fn default() -> OptionSelectionState

Returns the “default value” for a type.

impl From<Option<SelectionState>> for OptionSelectionState

fn from(o: Option<SelectionState>) -> OptionSelectionState

Converts to this type from the input type.

impl From<OptionSelectionState> for Option<SelectionState>

fn from(o: OptionSelectionState) -> Option<SelectionState>

Converts to this type from the input type.

impl PartialEq for OptionSelectionState

fn eq(&self, other: &OptionSelectionState) -> 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.
