Struct ProjectionEngine 

pub struct ProjectionEngine<'a> { /* private fields */ }

Pure projection coordinator over a sealed world and federated closure.

Implementations

impl<'a> ProjectionEngine<'a>

pub fn new( registry: &'a ProjectionRegistry, shapes: &'a dyn ConfigShapeVerifier, closure: &'a FederatedClosure, ) -> Self

Binds the loaded registry, Shape verifier, and sealed closure.

pub fn project( &self, world: &ObservedWorld, spec: &ProjectionSpec, policy: &ProjectorPolicy, confinement: Option<ConfinementEvidence>, ) -> Result<ProjectionResult, ProjectionError>

Runs one qualified projection without acquiring observation or effects.

Qualification is not a caller-suppliable parameter: it is fetched from this engine’s own bound registry, for this exact registered provider instance, at the moment of dispatch. A caller cannot obtain a qualification once and replay it later, against this registry after the provider changed, or against a different registry entirely – there is no value of that shape for it to hold or pass.

Errors

Returns ProjectionError::UnqualifiedProjector if spec.kind was never granted bootstrap admission, or if the underlying receipt is no longer current.
