Struct StreamingCompletionResponse 

pub struct StreamingCompletionResponse {
    pub usage: PartialUsage,
    pub stop_reason: Option<String>,
    pub stop_sequence: Option<String>,
    pub message_id: Option<String>,
    pub model: Option<String>,
    pub provider_request_id: Option<String>,
}

Anthropic’s own terminal stream record, as returned by [GenericCompletionModel::raw_stream].

crate::completion::CompletionModel::stream maps this once into the normalized StreamFinal; callers who want the provider-native shape read it here instead.

Fields

usage: PartialUsage

Token usage carried by the terminal message_delta event.

stop_reason: Option<String>

Anthropic’s stop_reason, verbatim, when the stream reported one.

stop_sequence: Option<String>

Which of the caller’s stop_sequences actually fired, verbatim, when the terminal message_delta reported one.

stop_reason: "stop_sequence" says only that a sequence matched; the sequence itself is the part a caller branches on, and Anthropic strips it from the text, so the wire is its only source. The blocking twin has carried it on CompletionResponse::stop_sequence all along — the streamed record dropped it after parsing, so the same request answered strictly less when streamed.

message_id: Option<String>

The message_start message ID, when the stream reported one.

model: Option<String>

The model named by message_start, when the stream reported one.

provider_request_id: Option<String>

The transport request id from the SSE connection’s request-id response header — not part of any stream frame; stamped by the transport. None when the provider did not report one.
