task.rs

A lightweight periodic task scheduler. Does not rely on Rust nightly features. Currently only supports minute-level scheduling of tasks.

This is not ready for wide usage.

TODO

• Handle timezones appropriately
• Support for second-resolution cron schedules
• Ability to prevent job execution from stacking (won't reschedule until job completes)
• Tests!
• Better API
• Clean up code (esp. better concurrency) and make safer
