Implementations§

Source§

impl SignalProcessing

Source

pub async fn elements(&self) -> Result<Option<Vec<Element>>, Error>

Returns this device’s signal processing elements, or None if the device does not support signal processing.

Source

pub async fn topologies(&self) -> Result<Option<Vec<Topology>>, Error>

Returns this device’s signal processing topologies, or None if the device does not support signal processing.

Source

pub async fn topology_id(&self) -> Option<TopologyId>

Returns the current signal processing topology ID, or None if the device does not support signal processing.

Source

pub async fn element_state(&self, element_id: ElementId) -> Option<ElementState>

Returns the state of the signal processing element with the given element_id.

Returns None if there is no element with the given ID, or if the device does not support signal processing.

Source

pub async fn element_states(&self) -> Option<BTreeMap<ElementId, ElementState>>

Returns states of all signal processing elements, or None if the device does not support signal processing.
