Struct WidgetCaches 

pub struct WidgetCaches {
    pub extension: ExtensionCaches,
    /* private fields */
}

Per-widget mutable state that persists across renders.

Fields are pub(crate) to avoid leaking internal HashMap structure to extension authors. The renderer binary accesses specific entries through the accessor methods below.

Fields

extension: ExtensionCaches

Extension-owned caches. Public so extension authors can access their own cached state during render/prepare/cleanup.

Implementations

impl WidgetCaches

pub fn new() -> Self

pub fn clear_builtin(&mut self)

Clear per-node widget caches without touching extension caches.

Used by the Snapshot handler so that extension cleanup callbacks (via ExtensionDispatcher::prepare_all) can run before the extension cache entries are removed.

impl WidgetCaches

pub fn clear(&mut self)

pub fn editor_content_mut(&mut self, id: &str) -> Option<&mut Content>

Get a mutable reference to a text_editor Content by node ID.

pub fn pane_grid_state_mut(&mut self, id: &str) -> Option<&mut State<String>>

Get a mutable reference to a pane_grid State by node ID.

pub fn pane_grid_state(&self, id: &str) -> Option<&State<String>>

Get an immutable reference to a pane_grid State by node ID.

Trait Implementations

impl Default for WidgetCaches

fn default() -> Self

Returns the “default value” for a type.
