Struct TokenChunk 

pub struct TokenChunk {
    pub request_id: String,
    pub text_delta: String,
    pub tool_call_delta: Option<Value>,
    pub usage: Option<TokenUsage>,
    pub finish_reason: Option<FinishReason>,
}

One streamed chunk. Local runtimes emit one per generated token (or per micro-batch); remote runtimes emit one per provider SSE event.

Fields

request_id: String

text_delta: String

tool_call_delta: Option<Value>

Tool-call delta (provider-specific JSON). Carried opaquely through the runtime; only the gateway interprets it.

usage: Option<TokenUsage>

finish_reason: Option<FinishReason>
