Fields

origin: RequestOrigin

Open origin data describing who asked for eval.

codec: Symbol

Codec symbol used to decode text or bytes sources.

source: ReadEvalSource

Source to decode and evaluate, or an already-decoded expression.

read_policy: ReadPolicy

Trusted host-built read policy; never derive this from request text.

requires: Vec<CapabilityName>

Capabilities the caller must already hold before eval can run.

allow: CapabilitySet

Maximum powers the request allows the eval body to run with.

expected_shape: Arc<dyn Shape>

Shape the evaluated result must satisfy before it is admitted.
