I Built a Fail-Fast Rust Scheduler with Background OAuth Auto-Refresh (Part 2)
The article discusses the implementation of a Fail-Fast Rust scheduler for a private backend powering developer tools. It addresses the challenges of silent scheduling failures and expiring OAuth tokens. The author details the architectural decisions made to ensure that users have connected their OAuth accounts before scheduling posts.
- ▪The Rust backend powers 18 developer tools and includes a multi-tier scheduling system.
- ▪Silent scheduling failures occur when users attempt to schedule posts without connecting their social media accounts via OAuth.
- ▪A Strict Separation model was implemented to verify OAuth credentials before allowing scheduling actions.
