Struct DomainCodecLib 

pub struct DomainCodecLib { /* private fields */ }

A host-registered lib that exports one codec (and optionally the Shapes it uses) built from a decoder and encoder.

Implementations

impl DomainCodecLib

pub fn new( symbol: Symbol, codec_id: CodecId, decoder: Arc<dyn Decoder>, encoder: Arc<dyn Encoder>, expr_shape_symbol: Symbol, ) -> Self

Build a domain codec lib. expr_shape_symbol is the codec’s expression shape; it is resolved (at load) from the lib’s own registered shapes, then the registry, then core/Expr, then core/Any, then nil.

pub fn with_shapes(self, shapes: Vec<(Symbol, ShapeRef)>) -> Self

Also register these Shapes when the lib loads (for codecs like codec:scene that own their domain’s node Shapes).

Trait Implementations

impl Lib for DomainCodecLib

fn manifest(&self) -> LibManifest

Returns the library’s manifest.

fn load(&self, _cx: &mut LoadCx, linker: &mut Linker<'_>) -> Result<()>

Registers the library’s exports against the registry via linker.

fn unload(&self, _cx: &mut Cx, _linker: &mut Linker<'_>) -> Result<(), Error>

Tears down external resources that cannot be represented in the registry’s recorded load delta.
