Struct FileRenderCacheStore 

pub struct FileRenderCacheStore { /* private fields */ }

File-backed render-page cache store.

Cache paths are deterministic by pagination profile and chapter index: <root>/<profile-hex>/chapter-<index>.json.

The store uses a JSON envelope with a schema version and enforces max_file_bytes on both reads and writes. When I/O, decode, or size checks fail, operations return None/no-op instead of bubbling errors.

Implementations

impl FileRenderCacheStore

pub fn new(root: impl Into<PathBuf>) -> Self

Create a new cache store rooted at root.

pub fn with_max_file_bytes(self, max_file_bytes: usize) -> Self

Set the maximum allowed cache file size in bytes.

Values of 0 are treated as 1 to keep the cap explicit.

pub fn cache_root(&self) -> &Path

Root directory for cache files.

pub fn max_file_bytes(&self) -> usize

Maximum allowed cache file size in bytes.

pub fn chapter_cache_path( &self, profile: PaginationProfileId, chapter_index: usize, ) -> PathBuf

Deterministic cache path for profile/chapter payload.
