Server-Sent Event payload emitted during an agent session run.

Variants

Message

A full role-tagged message, with content broken into typed blocks. Modeled on Claude Agent SDK’s AssistantMessage / UserMessage streaming shape so the TS / Python SDKs can yield typed messages without falling back to the session detail endpoint.

Fields

role: String

content: Vec<SseContentBlock>

PartialMessage

A partial text delta during streaming. Concatenate text deltas keyed by step to reconstruct the eventual Message::Text block.

Fields

text: String

step: usize

ToolCall

A tool is being called.

Fields

name: String

step: usize

ToolResult

A tool call completed.

Fields

name: String

success: bool

Done

The agent run completed.

Fields

finish_reason: String

total_steps: usize

Error

An error occurred.

Fields

message: String

PlanProposed

Agent proposed a plan and is waiting for human review.

Fields

plan: String

GoalContinuing

Goal-168: judge found condition not yet met; loop continues.

Fields

reason: String

turns: u32

GoalAchieved

Goal-168: judge confirmed condition met.

Fields

condition: String

turns: u32

ToolProgress

SDK Phase B: a tool call just completed; elapsed_ms is wall-clock time from when the ToolCall event was received to when ToolResult arrived. Emitted in addition to (and after) the tool_result event.

Fields

tool_use_id: String

tool_name: String

elapsed_ms: u64

Trait Implementations

impl Clone for SseEvent

fn clone(&self) -> SseEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SseEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SseEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SseEvent

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
