rrq_task_result

R Documentation

Fetch single task result

Description

Get the result for a single task (see rrq_task_results for a method for efficiently getting multiple results at once). Returns the value of running the task if it is complete, and an error otherwise.

Usage

rrq_task_result(task_id, error = FALSE, follow = NULL, controller = NULL)

Arguments

`task_id`	The single id for which the result is wanted.
`error`	Logical, indicating if we should throw an error if a task was not successful. By default (`error = FALSE`), in the case of the task result returning an error we return an object of class `rrq_task_error`, which contains information about the error. Passing `error = TRUE` calls `stop()` on this error if it is returned.
`follow`	Optional logical, indicating if we should follow any redirects set up by doing rrq_task_retry. If not given, falls back on the value passed into the controller, the global option `rrq.follow`, and finally `TRUE`. Set to `FALSE` if you want to return information about the original task, even if it has been subsequently retried.
`controller`	The controller to use. If not given (or `NULL`) we'll use the controller registered with `rrq_default_controller_set()`.
