Struct MarkdownRenderCache 

pub struct MarkdownRenderCache { /* private fields */ }

Bounded LRU cache for render_markdown output.

Stores the most recent rendered markdown slices keyed by a content fingerprint and target width. Keeping several entries avoids cache thrash when one frame renders transcript text alongside summary, review, or footer markdown blocks. Interior mutability via RefCell allows cache updates through shared references so the cache can be threaded through immutable render contexts without requiring &mut at every call site.

Cached values are stored as Arc<[Line<'static>]> so cache hits can reuse the rendered slice without cloning every line. Callers only clone Line values when they need to append the cached content into a larger output buffer.

Implementations

impl MarkdownRenderCache

pub fn render(&self, text: &str, width: usize) -> Arc<[Line<'static>]>

Returns cached rendered lines when the text hash, width, and cache version match; otherwise renders fresh and updates the cache.

pub fn bump_version(&self)

Bumps the cache version and drops all rendered entries.

Callers use this when non-content render settings change; the active theme is already part of each cache key.

Trait Implementations

impl Default for MarkdownRenderCache

fn default() -> Self

Returns the “default value” for a type.
