Struct ChannelHandler

pub struct ChannelHandler { /* private fields */ }

Protocol handler

Implementations

impl ChannelHandler

pub fn dbid(&self) -> u64

A unique ID for this channel

Trait Implementations

impl Handler for ChannelHandler

fn do_handle(&self, msg: Message) -> Result<Box<dyn SerBolt>>

Actual handling

fn client_id(&self) -> u64

Unused

fn for_new_client( &self, _client_id: u64, _peer_id: PubKey, _dbid: u64, ) -> ChannelHandler

Create a channel handler

fn node(&self) -> &Arc<Node>

Get the associated signing node. Note that if you want to perform an operation that can result in a mutation of the node state requiring a persist, and your persister writes to the cloud, you must use Handler::with_persist instead.

fn handle(&self, msg: Message) -> Result<Box<dyn SerBolt>>

Handle a message

fn commit(&self)

Commit the persister transaction if any

fn with_persist(&self, f: impl FnOnce(&Node) -> Result<()>) -> Result<Mutations>

Perform an operation on the Node that requires persistence. The operation must not mutate if it fails (returns an error). You must call Handler::commit after you persist the mutations in the cloud.
