• Type-safe — Strong typing with serde serialization/deserialization
• Typed handlers — Generic register_typed::<T>() for compile-time arg safety
• Middleware — Tower-inspired middleware chain for cross-cutting concerns (logging, tracing, metrics, OpenTelemetry)
• Workflows — Chain, Group, and Batch workflow primitives
• Builder pattern — Ergonomic client and worker configuration
• Full OJS compliance — Implements OJS v1.0 specification

Installation

[dependencies]
ojs = "0.1"
tokio = { version = "1", features = ["full"] }
