    },
    MessageStop,
    Ping,
    Error {
        error: ApiErrorBody,
    },
}

All possible SSE event types from the Claude streaming API. Each variant matches an event: <name> line in the SSE stream.

Variants

MessageStart

First event - contains the message skeleton (id, model, usage)

Fields

message: MessagesResponse

ContentBlockStart

A new content block is starting at the given index

Fields

index: usize

content_block: ContentBlock

ContentBlockDelta

Incremental content for the block at the given index

Fields

index: usize

delta: ContentDelta

ContentBlockStop

The block at the given index is complete

Fields

index: usize

MessageDelta

Message-level update (stop_reason, final usage)

Fields

delta: MessageDeltaPayload

usage: Option<Usage>

MessageStop

Message is complete - stream will end after this

Ping

Keepalive ping (ignore)

Error

Server-side error delivered via the stream

Fields

error: ApiErrorBody
