Implementations

impl ScenePck

pub fn load_and_rebuild( path: &Path, opt: &ScenePckDecodeOptions, ) -> Result<Self>

pub fn load_and_rebuild_from_bytes( tmp: Vec<u8>, opt: &ScenePckDecodeOptions, ) -> Result<Self>

pub fn load_lazy(path: &Path, opt: &ScenePckDecodeOptions) -> Result<Self>

Opens a pack without rebuilding it: scenes stay compressed (a quarter of the rebuilt size for RewriteHF, 11 MiB instead of 43) and are decompressed when a scene is first used.

pub fn load_lazy_from_bytes( tmp: Vec<u8>, opt: &ScenePckDecodeOptions, ) -> Result<Self>

pub fn is_lazy(&self) -> bool

Whether scenes are decompressed on demand (load_lazy).

pub fn scn_data_slice(&self, scn_no: usize) -> Result<Cow<'_, [u8]>>

A scene’s bytecode (decompressed first for a lazily loaded pack).

pub fn scn_data_shared( &self, scn_no: usize, ) -> Result<(Arc<Vec<u8>>, Range<usize>)>

Return shared backing storage plus the scene-local byte range. SceneStream uses this to borrow directly from the rebuilt Scene.pck (or, lazily loaded, from the scene’s own decompressed buffer) without copying or leaking each visited scene chunk.

pub fn find_scene_no(&self, name_or_index: &str) -> Option<usize>

pub fn find_scene_name(&self, scn_no: usize) -> Option<&str>

pub fn find_inc_cmd_no(&self, cmd_name: &str) -> Option<usize>
