Struct linuxvideo::stream::ReadStream

source · [−]

pub struct ReadStream { /* private fields */ }

Expand description

A stream that reads data from a V4L2 device.

Implementations

source

impl ReadStream

source

pub fn dequeue<T>(
&mut self,
cb: impl FnOnce(ReadBufferView<'_>) -> Result<T>
) -> Result<T>

Dequeues a buffer, passes it to cb, then enqueues it again.

If cb returns an error, this function will still try to enqueue the buffer again. If that fails, the error that occurred during enqueuing will be returned, if it succeeds, the error returned by cb will be returned.
