Enum DerivedGrantError 

pub enum DerivedGrantError {
    InvalidTopic {
        topic: String,
    },
}

Failure modes for NodeRegistry::issue_derived_grant.

Variants

InvalidTopic

The topic is empty or contains a / — topics name a single segment immediately below _derived/. Multi-segment grants must use GrantScope::TopicPrefix over the first segment and rely on path matching for finer granularity.

Fields

topic: String

The offending topic string.
