Struct WeightMaterializerRegistry 

pub struct WeightMaterializerRegistry { /* private fields */ }

Process-local registry retaining the exact implementations authorized to transform checkpoint schemas. It is deliberately neither serializable nor reconstructible from a capability catalog.

Implementations

impl WeightMaterializerRegistry

pub fn new( materializers: Vec<Box<dyn WeightMaterializer>>, ) -> Result<Self, VNextError>

pub fn identity_only() -> Result<Self, VNextError>

pub fn augment_catalog( &self, catalog: CapabilityCatalog, ) -> Result<CapabilityCatalog, VNextError>

Extends a capability catalog with descriptors from these exact process-local implementation objects.

pub fn select_exact( &self, family: &PreparedModelFamily, catalog: &CapabilityCatalog, materializer_id: &WeightMaterializerId, ) -> Result<TrustedExecutionWeightPlan, VNextError>

Invokes the selected trusted implementation and returns a witness that cannot be forged by deserializing an ExecutionWeightPlan. Selects a materializer that is value-preserving by contract.

Approximate transforms require a future typed quality approval carrying checked-in numerical-tolerance evidence. Keeping that authority out of this entrypoint prevents a build feature or backend capability from silently changing checkpoint precision.

pub fn descriptors( &self, ) -> BTreeMap<WeightMaterializerId, WeightMaterializerDescriptor>
