Module lightning::ln::features [−][src]
Expand description
Feature flag definitions for the Lightning protocol according to BOLT #9.
Lightning nodes advertise a supported set of operation through feature flags. Features are
applicable for a specific context as indicated in some messages. Features encapsulates
behavior for specifying and checking feature flags for a particular context. Each feature is
defined internally by a trait specifying the corresponding flags (i.e., even and odd bits).
Whether a feature is considered “known” or “unknown” is relative to the implementation, whereas
the term “supports” is used in reference to a particular set of Features. That is, a node
supports a feature if it advertises the feature (as either required or optional) to its peers.
And the implementation can interpret a feature if the feature is known to it.
