Enum ListPatch 

pub enum ListPatch {
    Reload,
    RowSizeInvalidated(usize),
    ScrollToEnd,
    ScrollToRow(usize),
    Selected(Vec<usize>),
}

Variants

Reload

The row set changed (count/order/content): the host re-queries its ListSource.

RowSizeInvalidated(usize)

An Automatic-height row’s content size changed; the host re-measures just that row.

ScrollToEnd

Imperatively scroll the native list so its LAST row is fully visible (a chat timeline sticking to the newest message). No-op when the list is empty (docs/list.md).

ScrollToRow(usize)

Imperatively scroll the native list so this row is visible, realizing it if needed (docs/list.md). Clamped to the row count; no-op when the list is empty.

Selected(Vec<usize>)

Programmatic selection sync (row indices; empty = clear) — toolkits apply WITHOUT re-emitting a selection event, like every other programmatic sync.

Trait Implementations

impl Clone for ListPatch

fn clone(&self) -> ListPatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ListPatch

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

Formats the value using the given formatter.

impl PartialEq for ListPatch

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