pub fn support_hedge(metadata: &AdapterMetadata) -> Option<String>Expand description
The one-line stderr hedge for an adapter that is not Proven, or None when it is (SP4 design §7.2).
It lists every capability whose state is not Supported, in Capability::ALL order, using the
report’s own vocabulary. NotGuaranteed counts: leaving it out would have hidden the state the design
predicts for an adapter whose documented mechanism is ignored by part of the agent.
