Trait Implementations

impl Clone for OptionDragDelta

fn clone(&self) -> OptionDragDelta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionDragDelta

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

Formats the value using the given formatter.

impl Default for OptionDragDelta

fn default() -> OptionDragDelta

Returns the “default value” for a type.

impl From<Option<DragDelta>> for OptionDragDelta

fn from(o: Option<DragDelta>) -> OptionDragDelta

Converts to this type from the input type.

impl From<OptionDragDelta> for Option<DragDelta>

fn from(o: OptionDragDelta) -> Option<DragDelta>

Converts to this type from the input type.

impl PartialEq for OptionDragDelta

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

impl PartialOrd for OptionDragDelta

fn partial_cmp(&self, other: &OptionDragDelta) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
