Struct VariableList 

pub struct VariableList<K> {
    pub state: ListState,
    /* private fields */
}

A tail-following list that builds visible rows plus 500px of overscan. Keys must be unique. Call sync before rendering and invalidate when an offscreen item’s height changes. Use state.remeasure() after font changes.

Fields

state: ListState

Implementations

impl<K: Clone + Eq + 'static> VariableList<K>

pub fn sync(&self, next: Vec<K>)

Reconcile insertions/removals while retaining the visible item’s pixel anchor.

pub fn invalidate(&self, key: &K)

pub fn set_end_inset(&self, inset: Pixels)

Keep the scrollbar clear of floating controls at the bottom.

pub fn visible_range(&self) -> Range<usize>

pub fn scroll_to(&self, index: usize)

pub fn focus_item(&self, index: usize, focus: Option<FocusHandle>)

Keep keyboard interaction alive for a selected item outside the viewport.

pub fn render( &self, render: impl FnMut(usize, &mut Window, &mut App) -> AnyElement + 'static, on_visible: impl Fn(Range<usize>, &mut Window, &mut App) + 'static, ) -> Div
