    CurrentModeUpdate(CurrentModeUpdate),
    ConfigOptionUpdate(ConfigOptionUpdate),
    SessionInfoUpdate(SessionInfoUpdate),
    UsageUpdate(UsageUpdate),
}

Different types of updates that can be sent during session processing.

These updates provide real-time feedback about the agent’s progress.

See protocol docs: Agent Reports Output

AgentMessageChunk(ContentChunk)

A chunk of the agent’s response being streamed.

AgentThoughtChunk(ContentChunk)

A chunk of the agent’s internal reasoning being streamed.

ToolCall(ToolCall)

Notification that a new tool call has been initiated.

ToolCallUpdate(ToolCallUpdate)

Update on the status or results of a tool call.

Plan(Plan)

The agent’s execution plan for complex tasks. See protocol docs: Agent Plan

AvailableCommandsUpdate(AvailableCommandsUpdate)

Available commands are ready or have changed

CurrentModeUpdate(CurrentModeUpdate)

The current mode of the session has changed

See protocol docs: Session Modes

ConfigOptionUpdate(ConfigOptionUpdate)

Session configuration options have been updated.

Trait Implementations

impl Clone for SessionUpdate

fn clone(&self) -> SessionUpdate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionUpdate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SessionUpdate

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl IntoV2 for SessionUpdate

type Output = SessionUpdate

The corresponding v2 draft type.

fn into_v2( self, ) -> Result<<SessionUpdate as IntoV2>::Output, ProtocolConversionError>

Converts this value into the corresponding v2 draft type.

impl JsonSchema for SessionUpdate

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for SessionUpdate

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

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.
