NewScheduler gives us a new TreeScheduler and SchedulerMetrics when given an Executor, a SchedulableService, and zero or more options.

ValidSchedule returns an error if the cron string is invalid.

WithMaxConcurrentWorkers is an option that sets the max number of concurrent workers that a TreeScheduler will use.

WithOnErrorFn is an option that sets the error function that gets called when there is an error in a TreeScheduler.

WithTime is an option for NewScheduler that allows you to inject a clock.Clock from ben johnson's github.com/benbjohnson/clock library, for testing purposes.

Item is a task in the scheduler.

NoopScheduler is a no-op scheduler.

Schedule is an object a valid schedule of runs.

TreeScheduler is a Scheduler based on a btree.

Executor is a system used by the scheduler to actually execute the scheduleable item.

Schedulable is the interface that encapsulates work that is to be executed on a specified schedule.

SchedulableService encapsulates the work necessary to schedule a job.

Scheduler is a example interface of a Scheduler.

ErrorFunc is a function for error handling.

ID duplicates the influxdb ID so users of the scheduler don't have to import influxdb for the ID.
