Enum ndk::audio::AudioAllowedCapturePolicy

#[non_exhaustive]
#[repr(i32)]
pub enum AudioAllowedCapturePolicy {
    AllowCaptureByAll = 1,
    AllowCaptureBySystem = 2,
    AllowCaptureByNone = 3,
}

Available on crate features audio and api-level-29 only.

Specifying if audio may or may not be captured by other apps or the system.

Note that these match the equivalent values in android.media.AudioAttributes in the Android Java API.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AllowCaptureByAll = 1

Indicates that the audio may be captured by any app.

For privacy, the following usages can not be recorded: VoiceCommunication*, Notification*, Assistance* and Assistant.

On Android Q, this means only Media and Game may be captured.

See MediaProjection and AudioStreamBuilder::allowed_capture_policy().

AllowCaptureBySystem = 2

Indicates that the audio may only be captured by system apps.

System apps can capture for many purposes like accessibility, live captions, user guidance… but abide to the following restrictions:

• the audio cannot leave the device;
• the audio cannot be passed to a third party app;
• the audio cannot be recorded at a higher quality than 16kHz 16bit mono.

See AudioStreamBuilder::allowed_capture_policy().

AllowCaptureByNone = 3

Indicates that the audio may not be recorded by any app, even if it is a system app.

It is encouraged to use AllowCaptureBySystem instead of this value as system apps provide significant and useful features for the user (such as live captioning and accessibility).

Trait Implementations

impl Clone for AudioAllowedCapturePolicy

fn clone(&self) -> AudioAllowedCapturePolicy

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AudioAllowedCapturePolicy

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

Formats the value using the given formatter.

impl From<AudioAllowedCapturePolicy> for i32

fn from(enum_value: AudioAllowedCapturePolicy) -> Self

Converts to this type from the input type.

impl From<i32> for AudioAllowedCapturePolicy

fn from(number: i32) -> Self

Converts to this type from the input type.

impl FromPrimitive for AudioAllowedCapturePolicy

type Primitive = i32

fn from_primitive(number: Self::Primitive) -> Self

impl PartialEq for AudioAllowedCapturePolicy

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

This method tests for self and other values to be equal, and is used by ==.

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

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