Adds a lightweight client for polling one or more block sources for the
best chain tip. Notifies listeners of blocks connected or disconnected
since the last poll. Useful for keeping a Lightning node in sync with
the chain.
Add an interface for being notified of block connected and disconnected
events, along with a notifier for generating such events. Used while
polling block sources for a new tip in order to feed these events into
ChannelManager and ChainMonitor.
ChainPoller defines a strategy for polling a single BlockSource. It
handles validating chain data returned from the BlockSource. Thus, other
implementations of Poll must be defined in terms of ChainPoller.
SPV clients need to poll one or more block sources for the best chain
tip and to retrieve related chain data. The Poll trait serves as an
adaptor interface for BlockSource. Implementations may define an
appropriate polling strategy.
Implements a simple HTTP client that can issue GET and POST requests.
Used to implement REST and RPC clients, respectively. Both clients
support either blocking or non-blocking I/O.
Defines an interface and related types for fetching block headers and
data from a block source (e.g., Bitcoin Core). Used to keep lightning in
sync with chain activity.
