pub struct TxStream { /* private fields */ }Expand description
Owned HackRF transmit stream.
start selects TX while the radio is off. write owns the TX transport
directly and never changes direction or takes the lifecycle mutex.
Implementations§
Source§impl TxStream
impl TxStream
Sourcepub fn start(&mut self) -> impl MaybeFuture<Output = Result<()>> + '_
pub fn start(&mut self) -> impl MaybeFuture<Output = Result<()>> + '_
Start TX while the radio is off.
Returns Error::Busy when RX is active or any control transition is
in progress. Calling start on an already-running TX stream succeeds
without changing hardware state.
Sourcepub fn write<'a>(
&'a mut self,
samples: &'a [Complex32],
timeout: Option<Duration>,
end_burst: bool,
) -> impl MaybeFuture<Output = Result<usize>> + 'a
pub fn write<'a>( &'a mut self, samples: &'a [Complex32], timeout: Option<Duration>, end_burst: bool, ) -> impl MaybeFuture<Output = Result<usize>> + 'a
Queue normalized complex IQ samples on a started TX stream.
Blocking calls honor timeout; awaited calls use asynchronous USB and
ignore it. end_burst appends the terminal zero-filled flush used by
libhackrf. If a timeout leaves that flush pending, the next write or
stop submits it before accepting a later burst.
Sourcepub fn stop(
&mut self,
) -> impl MaybeFuture<Output = Result<TxStreamingStats>> + '_
pub fn stop( &mut self, ) -> impl MaybeFuture<Output = Result<TxStreamingStats>> + '_
Flush and drain accepted samples, then turn the radio off.
If the normal 16-transfer TX backpressure window is full, the terminal flush may temporarily submit one additional transfer before draining. This deliberately preserves the requested end-of-burst boundary.
A successful stop leaves the stream reusable. After a stream I/O
failure, stop still attempts to turn the radio off and permanently
invalidates this stream. If draining the endpoint fails, reopen the
device before transmitting again because its pending transfers cannot
be safely reused.
