Namespace: FsToolkit.ErrorHandling
Function Signature:
('a -> 'b) -> Async<Result<'c, 'a>> -> Async<Result<'c, 'b>>From the AsyncResult.map example, if we want to map the error part alone, we can do it as below:
// Async<Result<PostId>, string>
createPost createPostRequest
|> AsyncResult.mapError (fun (ex : exn) -> ex.Message)
