drag and drop actions

This is a bitmask of the available/preferred actions in a drag-and-drop operation.

In the compositor, the selected action is a result of matching the actions offered by the source and destination sides. "action" events with a "none" action will be sent to both source and destination if there is no match. All further checks will effectively happen on (source actions ∩ destination actions).

In addition, compositors may also pick different actions in reaction to key modifiers being pressed. One common design that is used in major toolkits (and the behavior recommended for compositors) is:

Behavior beyond that is considered implementation-dependent. Compositors may for example bind other modifiers (like Alt/Meta) or drags initiated with other buttons than BTN_LEFT to specific actions (e.g. "ask").

Methods

impl DndAction

pub const None: DndAction

no action

pub const Copy: DndAction

copy action

pub const Move: DndAction

move action

pub const Ask: DndAction

ask action

pub const fn empty() -> DndAction

Returns an empty set of flags

pub const fn all() -> DndAction

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<DndAction>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> DndAction

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: DndAction) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: DndAction) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: DndAction)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: DndAction)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: DndAction)

Toggles the specified flags in-place.

pub fn set(&mut self, other: DndAction, value: bool)

Inserts or removes the specified flags depending on the passed value.
