defmodule LLM.Stream.Error do
  @moduledoc """
  Error chunk from a streaming response.

  Emitted when the provider returns an error during streaming. The stream
  typically ends after an error chunk is received.

  ## Fields

  - `:message` — human-readable error description
  - `:code` — optional error code from the provider (e.g., `"rate_limit_exceeded"`)

  ## Example

      %LLM.Stream.Error{message: "Rate limit exceeded", code: "rate_limit_exceeded"}

  @type t :: %__MODULE__{
          message: String.t(),
          code: String.t() | nil
        }
