Struct ZoneRecord 

pub struct ZoneRecord<T: Clone + 'static> {
    pub id: ZoneId,
    pub parent: Option<ZoneId>,
    pub label: Option<String>,
    pub on_drop: Callback<DropOutcome<T>>,
    pub accepts: Option<Callback<T, bool>>,
    pub mounted: Option<Rc<MountedData>>,
    pub rect: Option<Rect>,
}

One registered drop zone.

Fields

id: ZoneId

parent: Option<ZoneId>

The enclosing zone, when this zone is nested inside another DropZone (discovered automatically via context).

label: Option<String>

Human label used in screen-reader announcements.

on_drop: Callback<DropOutcome<T>>

Delivers a completed drop to the zone’s owner.

accepts: Option<Callback<T, bool>>

The zone’s acceptance filter, if any.

mounted: Option<Rc<MountedData>>

The zone’s mounted element, once available. This plain value lives in the provider-owned registry storage; zones update it through ZoneRegistry::set_mounted.

rect: Option<Rect>

Cached client rect (refreshed via ZoneRegistry::refresh_rects). This plain value lives in the provider-owned registry storage; zones update it through ZoneRegistry::set_rect_if_present.

Implementations

impl<T: Clone + 'static> ZoneRecord<T>

pub fn accepts_payload(&self, payload: &T) -> bool

Does this zone accept the payload?

pub fn cached_rect(&self) -> Option<Rect>

The cached client rect in this registry snapshot.

pub fn mounted_handle(&self) -> Option<Rc<MountedData>>

The mounted element in this registry snapshot.

Trait Implementations

impl<T: Clone + 'static> Clone for ZoneRecord<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
