Available on crate features environments or participants or sessions only.

Audio encoding of the output audio format in Text-To-Speech.

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.

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.

Mp364Kbps

MP3 audio at 64kbps.

OggOpus

Opus encoded audio wrapped in an ogg container. The result will be 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.

Alaw

8-bit samples that compand 13-bit audio samples using G.711 PCMU/a-law.

UnknownValue(UnknownValue)

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

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

Implementations

impl OutputAudioEncoding

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 OutputAudioEncoding

fn clone(&self) -> OutputAudioEncoding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OutputAudioEncoding

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

Formats the value using the given formatter.

impl Default for OutputAudioEncoding

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OutputAudioEncoding

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for OutputAudioEncoding

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

Formats the value using the given formatter.

impl From<&str> for OutputAudioEncoding

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<i32> for OutputAudioEncoding

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for OutputAudioEncoding

fn eq(&self, other: &OutputAudioEncoding) -> 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 OutputAudioEncoding

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

where S: Serializer,

Serialize this value into the given Serde serializer.
