Struct hexodsp::monitor::MonitorBackend

pub struct MonitorBackend {
    rb_mon_prod: Producer<MonitorBufPtr>,
    rb_recycle_con: Consumer<MonitorBufPtr>,
    unused_monitor_buffers: Vec<MonitorBufPtr>,
}

Fields

rb_mon_prod: Producer<MonitorBufPtr>

rb_recycle_con: Consumer<MonitorBufPtr>

unused_monitor_buffers: Vec<MonitorBufPtr>

Holds enough monitor buffers to hold about 1-2 seconds of data. The MonitorBuf boxes are written in the backend and then sent via MonitorBackend::rb_mon_prod to the frontend. The frontend then sends the used MonitorBufPtr back via quick_update_con.

Implementations

impl MonitorBackend

pub fn check_recycle(&mut self)

Checks if there are any used monitor buffers to be collected.

pub fn get_unused_mon_buf(&mut self) -> Option<MonitorBufPtr>

Hands out an unused MonitorBuf for filling and sending to the MonitorProcessor thread.

pub fn count_unused_mon_bufs(&self) -> usize

A helper function for writing tests. Returns the number of MonitorBuf we can hand out until there are none anymore.

pub fn send_mon_buf(&mut self, buf: MonitorBufPtr)

Sends a MonitorBuf to the MonitorProcessor.
