Enum AudioEncoding 

#[non_exhaustive]
pub enum AudioEncoding {
    Unspecified,
    Linear16,
    Mp3,
    OggOpus,
    Mulaw,
    Alaw,
    Pcm,
    M4A,
    UnknownValue(UnknownValue),
}

Configuration to set up audio encoder. The encoding determines the output audio format that we’d like.

Working with unknown values

This enum is defined as #[non_exhaustive] because Google Cloud may add additional enum variants at any time. Adding new variants is not considered a breaking change. Applications should write their code in anticipation of:

• New values appearing in future releases of the client library, and
• New values received dynamically, without application changes.

Please consult the Working with enums section in the user guide for some guidelines.

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.

Unspecified

Not specified. Only used by GenerateVoiceCloningKey. Otherwise, will return result [google.rpc.Code.INVALID_ARGUMENT][google.rpc.Code.INVALID_ARGUMENT].

Linear16

Uncompressed 16-bit signed little-endian samples (Linear PCM). Audio content returned as LINEAR16 also contains a WAV header.

Mp3

MP3 audio at 32kbps.

OggOpus

Opus encoded audio wrapped in an ogg container. The result is a file which can be played natively on Android, and in browsers (at least Chrome and Firefox). The quality of the encoding is considerably higher than MP3 while using approximately the same bitrate.

Mulaw

8-bit samples that compand 14-bit audio samples using G.711 PCMU/mu-law. Audio content returned as MULAW also contains a WAV header.

Alaw

8-bit samples that compand 14-bit audio samples using G.711 PCMU/A-law. Audio content returned as ALAW also contains a WAV header.

Pcm

Uncompressed 16-bit signed little-endian samples (Linear PCM). Note that as opposed to LINEAR16, audio won’t be wrapped in a WAV (or any other) header.

M4A

M4A audio.

UnknownValue(UnknownValue)

If set, the enum was initialized with an unknown value.

Applications can examine the value using AudioEncoding::value or AudioEncoding::name.

Implementations

impl AudioEncoding

pub fn value(&self) -> Option<i32>

Gets the enum value.

Returns None if the enum contains an unknown value deserialized from the string representation of enums.

pub fn name(&self) -> Option<&str>

Gets the enum value as a string.

Returns None if the enum contains an unknown value deserialized from the integer representation of enums.

Trait Implementations

impl Clone for AudioEncoding

fn clone(&self) -> AudioEncoding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AudioEncoding

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

Formats the value using the given formatter.

impl Default for AudioEncoding

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AudioEncoding

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for AudioEncoding

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

Formats the value using the given formatter.

impl From<&str> for AudioEncoding

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<i32> for AudioEncoding

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for AudioEncoding

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

impl Serialize for AudioEncoding

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
