Struct AudioInputEvent

#[non_exhaustive]
pub struct AudioInputEvent {
    pub audio_chunk: Option<Blob>,
    pub content_type: String,
    pub event_id: Option<String>,
    pub client_timestamp_millis: i64,
}

Represents a chunk of audio sent from the client application to Amazon Lex V2. The audio is all or part of an utterance from the user.

Amazon Lex V2 accumulates audio chunks until it recognizes a natural pause in speech before processing the input.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

audio_chunk: Option<Blob>

An encoded stream of audio.

content_type: String

The encoding used for the audio chunk. You must use 8 KHz PCM 16-bit mono-channel little-endian format. The value of the field should be:

audio/lpcm; sample-rate=8000; sample-size-bits=16; channel-count=1; is-big-endian=false

event_id: Option<String>

A unique identifier that your application assigns to the event. You can use this to identify events in logs.

client_timestamp_millis: i64

A timestamp set by the client of the date and time that the event was sent to Amazon Lex V2.

Implementations

impl AudioInputEvent

pub fn audio_chunk(&self) -> Option<&Blob>

An encoded stream of audio.

pub fn content_type(&self) -> &str

The encoding used for the audio chunk. You must use 8 KHz PCM 16-bit mono-channel little-endian format. The value of the field should be:

audio/lpcm; sample-rate=8000; sample-size-bits=16; channel-count=1; is-big-endian=false

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

A unique identifier that your application assigns to the event. You can use this to identify events in logs.

pub fn client_timestamp_millis(&self) -> i64

A timestamp set by the client of the date and time that the event was sent to Amazon Lex V2.

impl AudioInputEvent

pub fn builder() -> AudioInputEventBuilder

Creates a new builder-style object to manufacture AudioInputEvent.

Trait Implementations

impl Clone for AudioInputEvent

fn clone(&self) -> AudioInputEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AudioInputEvent

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

Formats the value using the given formatter.

impl PartialEq for AudioInputEvent

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

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

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

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