source · pub struct Handle(/* private fields */);
Expand description
A handle used to communicate with the Overseer
.
Implementations§
source§impl Handle
impl Handle
sourcepub async fn block_imported(&mut self, block: BlockInfo)
pub async fn block_imported(&mut self, block: BlockInfo)
Inform the Overseer
that that some block was imported.
sourcepub async fn send_msg(
&mut self,
msg: impl Into<AllMessages>,
origin: &'static str,
)
pub async fn send_msg( &mut self, msg: impl Into<AllMessages>, origin: &'static str, )
Send some message to one of the Subsystem
s.
sourcepub async fn send_msg_anon(&mut self, msg: impl Into<AllMessages>)
pub async fn send_msg_anon(&mut self, msg: impl Into<AllMessages>)
Send a message not providing an origin.
sourcepub async fn block_finalized(&mut self, block: BlockInfo)
pub async fn block_finalized(&mut self, block: BlockInfo)
Inform the Overseer
that some block was finalized.
sourcepub async fn wait_for_activation(
&mut self,
hash: H256,
response_channel: Sender<Result<(), SubsystemError>>,
)
pub async fn wait_for_activation( &mut self, hash: H256, response_channel: Sender<Result<(), SubsystemError>>, )
Wait for a block with the given hash to be in the active-leaves set.
The response channel responds if the hash was activated and is closed if the hash was deactivated. Note that due the fact the overseer doesn’t store the whole active-leaves set, only deltas, the response channel may never return if the hash was deactivated before this call. In this case, it’s the caller’s responsibility to ensure a timeout is set.
