Enum Message 

pub enum Message {
    User(UserMessage),
    Assistant(AssistantMessage),
    System(SystemMessage),
    Result(ResultMessage),
    StreamEvent(StreamEvent),
}

Union type of all possible messages from the Claude Code CLI.

When receiving messages via ClaudeSdkClient::receive_message() or iterating results from query(), each message will be one of these variants.

Variants

User(UserMessage)

A user input message echoed back.

Assistant(AssistantMessage)

An assistant response with content blocks.

System(SystemMessage)

A system notification or status message.

Result(ResultMessage)

The final result message with cost/usage information.

StreamEvent(StreamEvent)

A partial streaming event (only when include_partial_messages is enabled).

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Message

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Message

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
