Struct ListDelete 

pub struct ListDelete {
    pub can_delete: Rc<dyn Fn(usize) -> bool>,
    pub delete_row: Rc<dyn Fn(usize)>,
}

The synchronous swipe-to-delete half of ListSource (docs/list.md), shaped exactly like ListReorder: both closures are called on the UI thread from inside native swipe callbacks, outside any day-core borrow, and run to completion synchronously.

Each platform spells the gesture its own way (a trailing swipe action on iOS, an ItemTouchHelper swipe on Android, a ListItem swipe action on ArkUI), but all three ask the same two questions, so this struct is one pair of closures rather than three shapes.

Fields

can_delete: Rc<dyn Fn(usize) -> bool>

May row index be deleted? Called before the affordance is offered, so a row the app protects shows no delete action at all rather than one that fails on use.

delete_row: Rc<dyn Fn(usize)>

Commit: delete row index. Removes it from Day’s row snapshot before returning (so len/token_at/bind_row already reflect the shorter list while the native row-removal animates) and defers the app’s own callback to the next event drain.

Trait Implementations

impl Clone for ListDelete

fn clone(&self) -> ListDelete

Returns a duplicate of the value.

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

Performs copy-assignment from source.
