Function Signature:

('a -> Task<Result<'b, 'c>>)

Examples

Note: Many use-cases requiring bind operations can also be solved using the taskResult computation expression.

Example 1

Continuing from the TaskResult.map2 example and given the function

let notifyFollowers : NotifyNewPostRequest -> Task<Result<unit,exn>>

we can notify all followers using TaskResult.bind as below:

newPostRequestResult |> TaskResult.bind notifyFollowers
