r_extcap::controls::asynchronous

Struct ExtcapControlReader

pub struct ExtcapControlReader { /* private fields */ }

Expand description

A reader for the Extcap control pipe.

Implementations§

impl ExtcapControlReader

pub async fn new(in_path: &Path) -> Self

Creates a new instance of ExtcapControlReader.

in_path: The path of the extcap control pipe passed with --extcap-control-in.

pub async fn read_control_packet( &mut self, ) -> Result<ControlPacket<'static>, ReadControlError>

Read one control packet, awaiting until the packet arrives. Since the control packet pipe is expected to stay open for the entire duration of the extcap program, if the pipe is closed prematurely in this function here, UnexpectedEof will be returned.
