Enum VirtualListKeyCacheMode 

pub enum VirtualListKeyCacheMode {
    AllKeys,
    VisibleOnly,
}

Variants

AllKeys

Cache the full index -> key mapping so we can:

• restore scroll anchor across reorder
• provide stable keys to measured virtualization

VisibleOnly

Do not cache index -> key. Keys are computed on-demand for visible items only.

This is intended for very large fixed-height lists (e.g. tables) where caching the full key map can dominate startup time and memory.

Trait Implementations

impl Clone for VirtualListKeyCacheMode

fn clone(&self) -> VirtualListKeyCacheMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VirtualListKeyCacheMode

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

Formats the value using the given formatter.

impl Default for VirtualListKeyCacheMode

fn default() -> VirtualListKeyCacheMode

Returns the “default value” for a type.

impl PartialEq for VirtualListKeyCacheMode

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