Enum ExternalDragPositionQuality 

pub enum ExternalDragPositionQuality {
    None,
    BestEffort,
    Continuous,
}

Quality of cursor/position updates during external OS drag sessions (e.g. file drag hover).

This is used to express degradation, not just availability: a backend may support external drops but not provide reliable per-frame hover coordinates.

Variants

None

External drag is unsupported (or position updates are unavailable).

BestEffort

The backend provides external drag events, but pointer positions are best-effort / may be stale or missing (e.g. macOS winit file DnD hover limitations).

Continuous

The backend provides reliable pointer position updates during external drag hover.

Implementations

pub fn as_str(self) -> &'static str

pub fn clamp_to_available(self, available: Self) -> Self

Trait Implementations

impl Clone for ExternalDragPositionQuality

fn clone(&self) -> ExternalDragPositionQuality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExternalDragPositionQuality

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

Formats the value using the given formatter.

impl Default for ExternalDragPositionQuality

fn default() -> ExternalDragPositionQuality

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ExternalDragPositionQuality

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ExternalDragPositionQuality

fn eq(&self, other: &ExternalDragPositionQuality) -> 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 Serialize for ExternalDragPositionQuality

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ExternalDragPositionQuality
