Struct StreamEvent 

pub struct StreamEvent {
    pub event_type: String,
    pub data: Value,
    pub session_id: String,
}

A rich streaming event for data that does not map 1:1 to content blocks.

Used for tool call lifecycle events, plan updates, usage deltas, permission requests, and any other structured event the wire format emits between content blocks. The data field carries the raw JSON payload — consumers should match on event_type to deserialize it.

Fields

event_type: String

Discriminator identifying what data contains.

data: Value

Raw event payload — structure depends on event_type.

session_id: String

Session this event belongs to.

Trait Implementations

impl Clone for StreamEvent

fn clone(&self) -> StreamEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StreamEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for StreamEvent

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
