Struct CaptureStatus 

pub struct CaptureStatus(/* private fields */);

A read-only view of a device’s captures.

Every client of the device reads it, through the server utilities, without reaching the device thread. It is asked before every launch that has to decide the same way in a capture’s warmup and its recording, so it can’t cost a round trip: with no capture under way on the device, it is one atomic load.

Implementations

impl CaptureStatus

pub fn any_active(&self) -> bool

Whether any stream of the device is preparing or recording a capture: when not, no logical stream is capturing, whichever it is.

pub fn any_recording(&self) -> bool

Whether any stream of the device records a graph.

pub fn is_capturing(&self, stream: StreamId) -> bool

Whether the logical stream is preparing or recording a graph capture, from graph_prepare until the capture ends however it ends.

It takes the record’s lock: a hot path asks any_active first.
