Functions

configure(opts)

configure!(opts)

delete_shape(request)

@spec delete_shape(Electric.Shapes.Api.Request.t()) ::
  Electric.Shapes.Api.Response.t()

@spec delete_shape(Plug.Conn.t()) :: Plug.Conn.t()

delete_shape(conn, request)

encode_error_message(api, message)

@spec encode_error_message(t() | Electric.Shapes.Api.Request.t(), term()) :: Enum.t()

encode_message(request, message)

@spec encode_message(Electric.Shapes.Api.Request.t(), term()) :: Enum.t()

if_not_modified(conn, request)

load_shape_info(request)

@spec load_shape_info(Electric.Shapes.Api.Request.t()) ::
  {:ok, Electric.Shapes.Api.Request.t()}
  | {:error, Electric.Shapes.Api.Response.t()}

Load or create the shape for a validated request, and seek to the correct offset.

Must be called with a request returned by validate_params/2.

options(conn)

@spec options(Plug.Conn.t()) :: Plug.Conn.t()

plug_opts(opts)

predefined_shape(api, shape_params)

@spec predefined_shape(t(), shape_opts()) :: {:ok, t()} | {:error, term()}

Create a version of the given configured Api instance that is specific to the given shape.

This allows you to provide a locked-down version of the API that ignores shape-definition parameters such as table, where and columns and only honours the shape-tailing parameters such as offset and handle.

schema(arg1)

serve_shape_log(request)

@spec serve_shape_log(Electric.Shapes.Api.Request.t()) ::
  Electric.Shapes.Api.Response.t()

Return shape log data.

serve_shape_log(conn, request)

serve_shape_response(request)

serve_shape_response(conn, request)

serve_subset_response(request)

stack_id(arg1)

@spec stack_id(
  t()
  | Electric.Shapes.Api.Request.t()
  | Electric.Shapes.Api.Response.t()
) :: String.t()

validate(api, params)

@spec validate(t(), %{required(atom() | binary()) => term()}) ::
  {:ok, Electric.Shapes.Api.Request.t()}
  | {:error, Electric.Shapes.Api.Response.t()}

Validate the parameters for the request and load/create the shape.

This is a convenience wrapper that calls validate_params/2 followed by load_shape_info/1. Use the individual functions when you need to perform actions (like admission control) between validation and shape creation.

validate_for_delete(api, params)

@spec validate_for_delete(t(), %{required(atom() | binary()) => term()}) ::
  {:ok, Electric.Shapes.Api.Request.t()}
  | {:error, Electric.Shapes.Api.Response.t()}

validate_params(api, params)

@spec validate_params(t(), %{required(atom() | binary()) => term()}) ::
  {:ok, Electric.Shapes.Api.Request.t()}
  | {:error, Electric.Shapes.Api.Response.t()}

Validate request parameters without creating or loading a shape.

Returns a validated Request with parsed parameters and shape definition, but no shape handle. Call load_shape_info/1 afterwards to create or look up the shape.
