Trait cognitive_services_speech_sdk_rs::audio::PushAudioOutputStreamCallbacks

pub trait PushAudioOutputStreamCallbacks: Send {
    fn write(&mut self, data_buffer: &[u8]) -> u32;
    fn close(&mut self);
}

This trait that must be implemented by callback struct passed into push audio output stream during initialization. Methods of this trait will be called by Speech Synthetizer. When Synthetizer has syntehtized data it will call write method.
Structs implementing PushAudioOutputStreamCallbacks must also implement Send trait.
To see how to use see example: synthesizer/speak_ssml_async.

Required Methods

fn write(&mut self, data_buffer: &[u8]) -> u32

called by synthetizer when new data are synthetized callback implementation should then write data to target sink (whatever it is) as appropriate It should return number of received bytes (in most cases it will return data_buffer.len())

fn close(&mut self)

Closes underlying resources of struct implementing this trait.
