Features

Methods for creating results are located on the Res class. Values can also be implicitly cast to Res instances. Methods like Map or Bind are available as extension methods on Res instances for easy chaining.

Res are immutable reference-types. They are compared using equality even when using ==.

Result instantiation

  • Ok
  • Fail
  • FromOp

Success and Fail results may also be implicitly cast from their containing values like this Res<int, string> res = 0

Result extension methods

  • IsOk
  • IsFail
  • Match (for functions and actions)
  • Bind
  • Map
  • MapError

Async mapping

There are also async versions of

  • Map
  • Bind
  • MapError

They are found by simply adding "Async" to the end of the method-name

There are also extension methods for Task<Res<_,_>> such as

  • MapAsyncRes
  • MapAsyncResError
  • BindAsyncRes
  • BindAsyncResAsync
