Provides a reusable Rust repository pattern and data access layer using sqlx, PgPool, and transaction/retry primitives, enabling reliable database operations in backend services.
Create a Rust project, wire a PgPool into VideoRepository, and run a sample that claims a batch and updates statuses.

A Rust repository pattern with sqlx structures data access around typed queries and a PgPool connection, providing a reusable abstraction layer that standardizes database interactions and ensures reliable state updates across backend services.
FOR UPDATE SKIP LOCKED coordinates concurrent workers by atomically claiming available rows during batch processing, preventing multiple Rust workers from processing the same database records simultaneously while allowing safe parallel execution.
Handling sqlx transient errors requires robust retry logic with exponential backoff and jitter, allowing Rust backend services to automatically recover from temporary database connection failures without manual intervention.
Yes, heartbeat-based staleness detection identifies inactive processing tasks within a Rust postgres pooling setup, enabling automatic resets of stale statuses on startup to maintain reliable state updates and prevent worker lockups.
Yes, the Rust data access layer supports a read-only test mode for safe validation, allowing developers to test typed queries and fixtures against the sqlx PgPool without modifying persistent database state or risking data corruption.
