Struct Delete 

pub struct Delete { /* private fields */ }

Swipe-to-delete for a list() (docs/list.md): the handler that applies a committed delete, the label the platform puts on its affordance, an optional per-row guard, and whether the gesture is offered right now. A list is deletable exactly when it carries one of these (list(..).deletable(Delete::new(f))).

The platform’s delete gesture does the work (the iOS trailing swipe action, Android’s ItemTouchHelper swipe, ArkUI’s ListItem swipe action) where the backend supports it (probe Cap::ListDelete). The desktop toolkits answer Unsupported, so a list that must be editable everywhere pairs this with an explicit control (a menu item or a button).

Implementations

impl Delete

pub fn new(deleted: impl Fn(usize) + 'static) -> Delete

deleted(index) runs after a committed delete: row index is gone. Apply the same removal to the backing data (v.remove(index)), and persist it if the change should survive a relaunch. Runs on the main thread at the next event drain, never inside the native swipe callback.

pub fn label<M>(self, text: impl IntoText<M>) -> Delete

The word the platform puts on its delete affordance (res::str::delete()). Resolved in the locale current when the list builds. Left unset, each backend falls back to a trash glyph rather than shipping an English word into every locale.

pub fn guard(self, g: impl Fn(usize) -> bool + 'static) -> Delete

Protect individual rows: called synchronously before the affordance is offered, so a row that answers false shows no delete action rather than one that fails on use. Keep it pure; it runs inside the platform’s swipe callback.

pub fn enabled<M>(self, on: impl IntoReactive<bool, M>) -> Delete

Whether the gesture is offered right now (default true): a constant or a reactive bool, read when the platform asks whether a row may be deleted.

Trait Implementations

impl Clone for Delete

fn clone(&self) -> Delete

Returns a duplicate of the value.

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

Performs copy-assignment from source.
