符號

符號	簽名／內容
`StreamEvent`	`Type`、`TextDelta`、`ReasoningDelta`、`ToolCall`、`Usage`、`FinishReason`、`Err`
`StreamEventType`	`text` / `reasoning` / `tool_call` / `usage` / `done` / `error`
`ToolCallDelta`	`Index`、`ID`、`Name`、`Arguments`、`ThoughtSignature`
`StreamError`	`Provider`、`Code`、`Body`、`Err`；實作 `Error()` 與 `Unwrap()`
`ErrStreamUnsupported`	`error`
`OpenStream`	`func(ctx, client http.Client, url string, headers map[string]string, body map[string]any, label string) (http.Response, error)`
`StreamChat` / `StreamResponses`	`func(resp *http.Response, label string) <-chan StreamEvent`
`ResponsesStreamError`	`func(label, data string) error`
`ScanSSE`	`func(reader *bufio.Reader, handle func(event, data string) bool) error`
`TruncateFrame`	`func(data string) string`
上限常數	`StreamBodyLimit` 64 MiB、`ErrorBodyLimit` 8 KiB、`ErrorFrameLimit` 512 B、`JSONBodyLimit` 64 KiB
