Available on crate feature realtime only.

Events sent from the client to the realtime server.

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.

SessionUpdate

Update session configuration.

Fields

session: Value

Updated session configuration.

AudioDelta

Append audio to the input buffer.

Fields

event_id: Option<String>

Optional event ID.

audio: Vec<u8>

Audio data (raw bytes, serialized as base64 on the wire).

format: Option<AudioFormat>

Audio format metadata for multi-format pipelines and debugging. Skipped during serialization — the server infers format from the session config.

InputAudioBufferCommit

Commit the current audio buffer (manual mode).

InputAudioBufferClear

Clear the audio input buffer.

ConversationItemCreate

Send a text message or tool response.

Fields

item: Value

The conversation item (flexible JSON for provider compatibility).

ResponseCreate

Trigger a response from the model.

Fields

config: Option<Value>

Optional response configuration.

ResponseCancel

Cancel/interrupt the current response.

Message

A standard message using adk_core’s native Role and Part types.

Fields

role: String

Role of the message.

parts: Vec<Part>

Content parts of the message.

UpdateSession

Universal intent to update session configuration mid-flight.

This is treated as a runner/control-plane internal intent and should not be sent directly to providers without interception. By construction, it is explicitly untagged from serialization to guarantee it cannot leak onto the WebSocket wire.

Fields

instructions: Option<String>

New system instructions.

tools: Option<Vec<ToolDefinition>>

New tools definition.

Trait Implementations

impl Clone for ClientEvent

fn clone(&self) -> ClientEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClientEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ClientEvent

fn deserialize<__D>( __deserializer: __D, ) -> Result<ClientEvent, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ClientEvent

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
