Enum DropRegion 

pub enum DropRegion {
    Center,
    Top,
    Bottom,
    Leading,
    Trailing,
}

One of the five drop regions a DropTarget can expose. Each is independently enable-able and carries an optional hint.

Leading/Trailing are writing-direction-relative by intent; the v1 hit-test maps Leading→left and Trailing→right (LTR only — the framework exposes no writing direction on the layout/paint contexts yet, so RTL mirroring is a documented follow-up).

Variants

Center

The middle of the target — whatever the side zones don’t claim.

Top

The top edge strip.

Bottom

The bottom edge strip.

Leading

The leading edge strip (left in LTR).

Trailing

The trailing edge strip (right in LTR).

Implementations

impl DropRegion

pub const ALL: [DropRegion; 5]

All five regions, in the hit-test priority order (side zones before centre; leading→trailing→top→bottom among the sides).

pub fn is_side(self) -> bool

True for the four side (edge) zones — the ones sized by size_factor. Center is the leftover middle and is never a side zone.

Trait Implementations

impl Clone for DropRegion

fn clone(&self) -> DropRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DropRegion

impl Debug for DropRegion

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

Formats the value using the given formatter.

impl Eq for DropRegion

impl Hash for DropRegion

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DropRegion

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