Namespace: FsToolkit.ErrorHandling

Function Signature:

Job<Result<'a, 'b>> -> Job<Result<'a, 'c>> -> Job<Result<'a, ('b * 'c)>>

let jobErr1 = JobResult.error "error1"
let jobErr2 = JobResult.error "error2"

JobResult.zipError jobErr1 jobErr2
// job { return Error ("error1", "error2") }

Example 2

let jobOk = JobResult.singleton 42
let jobErr = JobResult.error "something went wrong"

JobResult.zipError jobOk jobErr
// job { return Ok 42 }

Example 3

let validateAge : Job<Result<int, string>>
let validateName : Job<Result<string, string>>

// Job<Result<int, (string * string)>>
JobResult.zipError validateAge validateName
