Struct LayoutCache

pub struct LayoutCache { /* private fields */ }

Per-engine paragraph layout cache layered over TextSystem.

Entries have no independent eviction policy; call LayoutCache::clear at lifecycle boundaries or let the owning engine drop the cache. Stored handles are cheap std::sync::Arc clones of prepared layouts.

Examples

use ailloli_ui_editor::layout::LayoutCache;
let mut cache = LayoutCache::default();
cache.clear();

Implementations

impl LayoutCache

Resolves and invalidates cached paragraph layouts.

pub fn clear(&mut self)

Removes every prepared paragraph layout from this cache.

This does not clear the separate cache owned by a [TextSystem].

Examples

use ailloli_ui_editor::layout::LayoutCache;
let mut cache = LayoutCache::default();
cache.clear();
