Crew worker.

Source: R/crew_worker.R
crew_worker.Rd

Launches a crew worker which runs a mirai daemon. Not a user-side function. Users should not call crew_worker() directly. See launcher plugins like crew_launcher_local() for examples.

Usage

crew_worker(
  settings,
  launcher,
  worker,
  instance,
  options_metrics = crew::crew_options_metrics()
)

Arguments

settings

Named list of arguments to mirai::daemon().

launcher

Character of length 1, name of the launcher.

worker

Positive integer of length 1, index of the worker. This worker index remains the same even when the current instance of the worker exits and a new instance launches.

instance

Character of length 1 to uniquely identify the current instance of the worker.

options_metrics

Either NULL to opt out of resource metric logging for workers, or an object from crew_options_metrics() to enable and configure resource metric logging for workers. For resource logging to run, the autometric R package version 0.1.0 or higher must be installed.

Value

NULL (invisibly)
