Enum ndk::audio::AudioContentType

#[non_exhaustive]
#[repr(i32)]
pub enum AudioContentType {
    Speech = 1,
    Music = 2,
    Movie = 3,
    Sonification = 4,
}

Available on crate features audio and api-level-28 only.

The ContentType attribute describes “what” you are playing. It expresses the general category of the content. This information is optional. But in case it is known (for instance Movie for a movie streaming service or Speech for an audio book application) this information might be used by the audio framework to enforce audio focus.

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.

Speech = 1

Use this for spoken voice, audio books, etcetera.

Music = 2

Use this for pre-recorded or live music.

Movie = 3

Use this for a movie or video soundtrack.

Sonification = 4

Use this for sound is designed to accompany a user action, such as a click or beep sound made when the user presses a button.

Trait Implementations

impl Clone for AudioContentType

fn clone(&self) -> AudioContentType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AudioContentType

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

Formats the value using the given formatter.

impl From<AudioContentType> for i32

fn from(enum_value: AudioContentType) -> Self

Converts to this type from the input type.

impl From<i32> for AudioContentType

fn from(number: i32) -> Self

Converts to this type from the input type.

impl FromPrimitive for AudioContentType

type Primitive = i32

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

impl PartialEq for AudioContentType

fn eq(&self, other: &AudioContentType) -> 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.
