Struct GeneratedFormatCache 

pub struct GeneratedFormatCache { /* private fields */ }

A cached snapshot of a generated engine format image for repeated instantiation.

Implementations

impl GeneratedFormatCache

pub fn empty() -> Self

Returns an empty format cache with no initialized state.

pub fn initialized(profile: EngineProfile) -> Self

Initializes a generated engine once and snapshots it as a reusable format cache.

pub fn from_engine(engine: &PortableTexEngine<'_>) -> Self

Snapshots the engine’s current format state into a reusable cache.

pub fn from_engine_owned(engine: PortableTexEngine<'_>) -> Self

Consumes an engine into a format cache by moving its state in place, avoiding a full clone.

pub fn image(&self) -> &PortableFormatImage

Returns a reference to the raw format image.

pub fn to_bytes(&self) -> Vec<u8>

Serializes the format image to a buffer valid for the same build target only.

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

Deserializes a format cache from a buffer produced by Self::to_bytes.

pub fn instantiate<'resources, R>( &self, profile: EngineProfile, resources: R, ) -> PortableTexEngine<'resources>

where R: ResourceProvider + 'resources,

Creates a new engine instance from this cached format image.
