Operators
JobResult Infix Operators
Namespace: FsToolkit.ErrorHandling.Operator.JobResult
FsToolkit.ErrorHandling provides the standard infix operators for the map
(<!>
), apply
(<*>
), and bind
(>>=
) functions of the Job<Result<_,_>>
type.
Examples:
Example 1
Expanding on the JobResult.map2 example, we define another function:
notifyFollowers : NotifyNewPostRequest -> Job<Result<unit, exn>>
We can then rewrite the example and additionally call notifyFollowers
using the operators as below:
open FsToolkit.ErrorHandling.Operator.JobResult
// CreatePostRequest -> Job<Result<unit, exn>>
let createPostAndNotifyFollowers (req : CreatePostRequest) =
notifyNewPostRequest
<!> (getFollowerIds req.UserId)
<*> (createPost req)
>>= notifyFollowers
