[−][src]Struct tokio_bus::BusReader
The BusReader
should not be manually crated,
but rather crated by calling add_rx()
on a Bus
.
A Bus
and BusReader
are both safe to drop at any time,
any messages not read by the BusReader
will not be lost
if the Bus
is dropped first, and if the BusReader
is
dropped first it will not block the Bus
's buffer.
Methods
impl<T: Clone + Sync> BusReader<T>
[src]
impl<T: Clone + Sync> BusReader<T>
pub fn new( | [src] |
Create a new BusReader
from a bus::BusReader
, a
handle to a task to register for writes to the Bus
and a handle to a task to notify when a read has
potentially caused buffer space in the Bus
to
become available.
