Typed event data enum for all event payloads

This enum provides type safety for event data. Each variant corresponds to a specific event type and contains the appropriate data structure. The Raw variant is used for backward compatibility with legacy events or unknown event types.

The data type depends on the event type field:

• input.message → InputMessageData
• output.message.started → OutputMessageStartedData
• output.message.delta → OutputMessageDeltaData
• output.message.completed → OutputMessageCompletedData
• turn.started → TurnStartedData
• turn.completed → TurnCompletedData
• turn.failed → TurnFailedData
• turn.cancelled → TurnCancelledData
• reason.started → ReasonStartedData
• reason.completed → ReasonCompletedData
• capability.usage → CapabilityUsageData
• act.started → ActStartedData
• act.completed → ActCompletedData
• tool.started → ToolStartedData
• tool.completed → ToolCompletedData
• tool.output.delta → ToolOutputDeltaData
• tool.call_requested → ToolCallRequestedData
• llm.generation → LlmGenerationData
• reason.thinking.started → ReasonThinkingStartedData
• reason.thinking.delta → ReasonThinkingDeltaData
• reason.thinking.completed → ReasonThinkingCompletedData
• reason.item → ReasonItemData
• session.started → SessionStartedData
• session.activated → SessionActivatedData
• session.idled → SessionIdledData
• session.title.updated → SessionTitleUpdatedData
• session.model.changed → SessionModelChangedData
• file.written → FileWrittenData

Unsupported

Internal-only variant for unknown event types. Never serialized to API responses - filtered out before transmission. Logs a warning when created to alert developers of unknown types.

Fields

event_type: String

The unknown event type string

data: Value

The raw JSON data

Implementations

impl EventData

pub fn needs_public_projection(&self) -> bool

Replace every carried message with its publishable projection, dropping the opaque provider replay state on reasoning parts.

The message read path already does this via Message::into_public, so without it here GET /v1/sessions/{id}/events would hand a client exactly the signature / encrypted material that GET /v1/sessions/{id}/messages withholds (EVE-933).

This is a read projection. The stored event must keep the replay state, because replaying a turn reconstructs the message from the event log. Whether Self::into_public would change this payload.

Lets a hot read path (the SSE stream) skip cloning for the many variants that carry no message. Keep in step with into_public.

pub fn into_public(self) -> Self

pub fn is_unsupported(&self) -> bool

Check if this is an unsupported event type. Unsupported events should be filtered before API responses.

pub fn unsupported(event_type: String, data: Value) -> Self

Create an unsupported event data with warning log. This is used when deserializing unknown event types.

impl EventData

pub fn event_type(&self) -> &'static str

Get the event type constant for this data. For Unsupported events, returns “unsupported” (internal use only).

impl EventData

pub fn voice_transcript_event( data: VoiceTranscriptData, event_type: &str, ) -> Self
