[−][src]Trait internet2::transport::RecvFrame
Frame receiving type which is able to parse raw data (streamed or framed by an underlying overlaid protocol such as ZMQ, HTTP, Websocket).
For asynchronous version check [AsyncRecvFrame
]
Required methods
pub fn recv_frame(&mut self) -> Result<Vec<u8>, Error>
[src]
Receive a single frame of data structured as a byte string. The frame contains LNP framing prefix, which is used by upstream session-level protocols.
Errors
Returns only [Error::SocketError
] if the overlaid protocol errors with
I/O error type
pub fn recv_raw(&mut self, len: usize) -> Result<Vec<u8>, Error>
[src]
Try to eceive len
number of bytes and pack them as a frame.
The actual amount of bytes received may differ for some protocols,
like ZMQ, so the function should be used with caution!
Errors
Returns only [Error::SocketError
] if the overlaid protocol errors with
I/O error type
Provided methods
pub fn recv_routed(&mut self) -> Result<RoutedFrame, Error>
[src]
Receive frame like with RecvFrame::recv_frame
, but only originating
from the specified remote address.
Returns
Tuple, consisting of two byte strings:
- Received frame
- Source of the frame (i.e. some id of the remote node that sent this frame). The id is specific for the underlying overlaid protocol.
Errors
Returns only [Error::SocketError
] if the overlaid protocol errors with
I/O error type
Panics
Default implementation panics, since most of the framing protocols do
not support multipeer sockets and [RecFrame::recv_frame
] must be
used instead (currently only ZMQ-based connections support this
operation)
