Struct BalloonTube

Source 
pub struct BalloonTube {
    tube: Tube,
    pending_queue: VecDeque<(BalloonControlCommand, Option<usize>)>,
    pending_adjust_with_completion: Option<(u64, usize)>,
}
Expand description

Utility for multiplexing a balloon tube between multiple control tubes. Commands are sent and processed serially.

Implementations§

Source§

impl BalloonTube

Source

pub fn new(tube: Tube) -> Self

Source

pub fn send_cmd( &mut self, cmd: BalloonControlCommand, key: Option<usize>, ) -> Option<(VmResponse, usize)>

Sends or queues the given command to this tube. Associates the response with the given key.

Source

pub fn recv(&mut self) -> Result<Vec<(VmResponse, usize)>>

Receives responses from the balloon tube, and returns them with their assoicated keys.
