Enum StreamEvent 

pub enum StreamEvent {
    Start {
        partial: AgentMessage,
    },
    Chunk(AssistantStreamChunk),
    Done {
        message: AgentMessage,
    },
    Error {
        partial: AgentMessage,
        kind: StreamErrorKind,
        message: String,
    },
}

Streamed event from the provider.

Streaming surface is rich because UIs need to render token-by-token. The loop folds these into a single StreamResponse at the end.

Variants

Start

First event. Provider has accepted the request and started generating. Carries the (so-far-empty) partial message so listeners can render an empty assistant placeholder.

Fields

partial: AgentMessage

Chunk(AssistantStreamChunk)

A streaming chunk. UI listeners render this; the loop folds it into the assembled message.

Done

Final event. Provider finished generating. Carries the assembled final message.

Fields

message: AgentMessage

Error

Final event. Provider raised an error during streaming. Carries the partial message produced so far and a human-readable error description. Stream implementations encode their typed errors here as strings; callers that need structured detail can parse kind.

Fields

partial: AgentMessage

kind: StreamErrorKind

message: String
