Module database 

The database driver: a jobs table, a failed_jobs table, and a reservation that is safe when several workers race for the same row.

Timestamps are stored as epoch seconds in bigint columns rather than as timestamptz. rustlavel-db deliberately leaves a timestamp column as text so precision survives, and a queue compares times far more often than it shows them: an integer sorts, compares and indexes without anything having to agree on a text format.

Structs

CreateJobProgressTable

CreateQueueTables

DatabaseProgress

Progress in a table. The one to use once the worker is its own process.

DatabaseQueue

A queue backed by two database tables.

Constants

FAILED_JOBS_TABLE

JOBS_TABLE

The conventional table names, matching Laravel’s.

JOB_PROGRESS_TABLE

Functions

create_tables

Create the queue’s two tables.

define_failed_jobs_table

The dead-letter table.

define_job_progress_table

Where a job’s progress is kept, so a worker in one process and a request handler in another read the same row.

define_jobs_table

The jobs table. A free function rather than a closure so a test can build the statements without a database, and see the same schema production gets.
