From: Valentine Wallace Date: Sat, 9 Nov 2019 01:12:13 +0000 (-0500) Subject: chaininterface: add BlockNotifier struct X-Git-Tag: v0.0.12~176^2~1 X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=969f8630133d8f53050d7ad48ca7a1450ebae08b;p=rust-lightning chaininterface: add BlockNotifier struct Adding this struct will allow us to remove the circular reference between ChainListeners and the ChainWatchInterface, because it separates out the responsibility of notifying listeners about new blocks from the responsibility of storing and retrieving watched transactions. --- diff --git a/lightning/src/chain/chaininterface.rs b/lightning/src/chain/chaininterface.rs index 24c9d7100..32fef48eb 100644 --- a/lightning/src/chain/chaininterface.rs +++ b/lightning/src/chain/chaininterface.rs @@ -193,6 +193,75 @@ impl ChainWatchedUtil { } } +/// Utility for notifying listeners about new blocks, and handling block rescans if new watch +/// data is registered. +pub struct BlockNotifier<'a> { + listeners: Mutex>>, //TODO(vmw): try removing Weak + chain_monitor: Arc, +} + +impl<'a> BlockNotifier<'a> { + /// Constructs a new BlockNotifier without any listeners. + pub fn new(chain_monitor: Arc) -> BlockNotifier<'a> { + BlockNotifier { + listeners: Mutex::new(Vec::new()), + chain_monitor, + } + } + + /// Register the given listener to receive events.
