mapOrElseAsync<U extends Object> method

Future<TaskResult<U, E>> mapOrElseAsync<U extends Object>(
  1. FutureOr<U> defaultValue(
    1. E error
    ),
  2. FutureOr<U> op(
    1. T data
    )
)

Mirrors to TaskResult.mapOrElseAsync.

Implementation

Future<TaskResult<U, E>> mapOrElseAsync<U extends Object>(FutureOr<U> Function(E error) defaultValue, FutureOr<U> Function(T data) op) => then((r) => r.mapOrElseAsync(defaultValue, op));
