}

Optional direct VJP rule expressed against primal semantic values.

Required Methods

fn family_id(&self) -> &'static str

Return the versioned extension family handled by this rule.

fn residual_mask(&self) -> ResidualSpec

Declare which primal input/output indices this rule reads as tensor residuals. Indices not declared may only be accessed through metadata.

fn primal_vjp( &self, request: SemanticPrimalVjpRequest<'_>, builder: &mut SemanticProgramBuilder, ) -> Result<Box<[AdValue]>, SemanticAdError>

Emit ordered optional input cotangents into builder.

Errors

Returns SemanticAdError::Unsupported when the payload is outside the rule’s supported domain, or SemanticAdError::Build when emitted semantic operations fail validation.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
