Concrete methods

def fromFunction[A, B](name: String)(f: A => B)(implicit ev: A <:< Request[Nothing, B]): DataSource[Any, A]

Constructs a data source from a pure function.

Constructs a data source from a pure function.

Attributes

def fromFunctionBatched[A, B](name: String)(f: Chunk[A] => Chunk[B])(implicit ev: A <:< Request[Nothing, B]): DataSource[Any, A]

Constructs a data source from a pure function that takes a list of requests and returns a list of results of the same size. Each item in the result list must correspond to the item at the same index in the request list.

Constructs a data source from a pure function that takes a list of requests and returns a list of results of the same size. Each item in the result list must correspond to the item at the same index in the request list.

Attributes

def fromFunctionBatchedOption[A, B](name: String)(f: Chunk[A] => Chunk[Option[B]])(implicit ev: A <:< Request[Nothing, B]): DataSource[Any, A]

Constructs a data source from a pure function that takes a list of requests and returns a list of optional results of the same size. Each item in the result list must correspond to the item at the same index in the request list.

Constructs a data source from a pure function that takes a list of requests and returns a list of optional results of the same size. Each item in the result list must correspond to the item at the same index in the request list.

Attributes

def fromFunctionBatchedWith[A, B](name: String)(f: Chunk[A] => Chunk[B], g: B => Request[Nothing, B])(implicit ev: A <:< Request[Nothing, B]): DataSource[Any, A]

Constructs a data source from a function that takes a list of requests and returns a list of results of the same size. Uses the specified function to associate each result with the corresponding effect, allowing the function to return the list of results in a different order than the list of requests.
