Module validate 

Validation for descriptors and subscription requests.

Structs

NegotiatedSubscription

Result of a successful subscription negotiation.

Enums

ValidationError

Reasons a descriptor or subscription request is refused.

Functions

negotiate_subscription

Negotiate a subscription against a feed descriptor’s advertised capabilities. Returns the chosen transport, format, and column projection on success; the caller pairs these with an endpoint to form a SubscribeAck.

validate_descriptor

Validate a descriptor in isolation: schema non-empty, at least one transport and one format advertised, and the declared event_time_key (when set) names an actual column.
