Enum Event 

pub enum Event {
    SessionStart(SessionStartEvent),
    TextDelta(TextDeltaEvent),
    Message(MessageEvent),
    ToolStart(ToolStartEvent),
    ToolEnd(ToolEndEvent),
    UsageDelta(UsageDeltaEvent),
    Result(ResultEvent),
    Error(ErrorEvent),
}

Unified event stream — the common language spoken by all agent adapters.

Every adapter translates its native streaming output into this enum so that consumers only need to handle one set of types regardless of which backend is running.

Variants

SessionStart(SessionStartEvent)

The agent session has been initialized.

TextDelta(TextDeltaEvent)

A chunk of assistant text (streaming delta).

Message(MessageEvent)

A complete assistant message.

ToolStart(ToolStartEvent)

The agent is invoking a tool.

ToolEnd(ToolEndEvent)

A tool invocation has completed.

UsageDelta(UsageDeltaEvent)

Incremental usage/cost update.

Result(ResultEvent)

The agent run has finished.

Error(ErrorEvent)

An error occurred during the run.

Implementations

impl Event

pub fn stamp(self) -> Self

Stamp the event with the current wall-clock time (epoch ms).

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Event

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Event

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Event

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

Formats the value using the given formatter.

impl PartialEq for Event

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
