Struct CacheState 

pub struct CacheState { /* private fields */ }

Available on crate feature markdown-preview only.

Cache state for markdown rendering.

Maintains two levels of caching:

• Parsed cache: Content-dependent, width-independent
• Render cache: Content and width-dependent

Implementations

impl CacheState

pub fn new() -> CacheState

Create a new cache state with empty caches.

pub fn clear_render_cache(&mut self)

Clear the render cache (e.g., when exiting filter mode).

pub fn invalidate(&mut self)

Invalidate both parsed and render caches.

Call this when content changes.

pub fn invalidate_render(&mut self)

Invalidate only the render cache.

Call this when width changes but content is the same.

pub fn parsed_cache(&self) -> Option<&ParsedCache>

Get a reference to the parsed cache if it exists.

pub fn render_cache(&self) -> Option<&RenderCache>

Get a reference to the render cache if it exists.

The render cache contains the rendered lines from the last render operation. This is useful for extracting text for copy operations.

pub fn set_parsed(&mut self, cache: ParsedCache)

Set the parsed cache.

pub fn set_render(&mut self, cache: RenderCache)

Set the render cache.
