-//! 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). A
-//! [`Context`] is used to parameterize [`Features`] and defines which features it can support.
-//!
-//! 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.
-//!
