ensure_queue: Make sure that a queue exists

In r-lib/liteq: Lightweight Portable Message Queue Using 'SQLite'

Make sure that a queue exists

Description

If it does not exist, then the queue will be created.

Usage

ensure_queue(name, db = default_db(), crash_strategy = "fail")

Arguments

name	Name of the queue. If not specified or NULL, a name is generated randomly.
db	Path to the database file.
crash_strategy	What to do with crashed jobs. The default is that they will "fail" (just like a negative acknowledgement). Another possibility is "requeue", in which case they are requeued immediately, potentially even multiple times. Alternatively it can be a number, in which case they are requeued at most the specified number of times.

Value

The queue object.
