Enum DeviceState

pub enum DeviceState {
    Active,
    Disabled,
    NotPresent,
    Unplugged,
}

Possible states for an [IMMDevice], an enum representing the DEVICE_STATE_XXX constants

Variants

Active

The audio endpoint device is active. That is, the audio adapter that connects to the endpoint device is present and enabled. In addition, if the endpoint device plugs int a jack on the adapter, then the endpoint device is plugged in.

Disabled

The audio endpoint device is disabled. The user has disabled the device in the Windows multimedia control panel, Mmsys.cpl

NotPresent

The audio endpoint device is not present because the audio adapter that connects to the endpoint device has been removed from the system, or the user has disabled the adapter device in Device Manager.

Unplugged

The audio endpoint device is unplugged. The audio adapter that contains the jack for the endpoint device is present and enabled, but the endpoint device is not plugged into the jack. Only a device with jack-presence detection can be in this state.

Trait Implementations

impl Debug for DeviceState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DeviceState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for DeviceState

fn eq(&self, other: &DeviceState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
