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). +//! See [`lightning_types::features`] for the list of features currently supported. //! -//! 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. +//! Note that the use of types via this module is deprecated and will be removed in a future +//! version.
