pulsar-rs: Future-based Rust client for Apache Pulsar

Documentation

This is a pure Rust client for Apache Pulsar that does not depend on the C++ Pulsar library. It provides an async/await based API, compatible with Tokio and async-std.

Features:

• URL based (pulsar:// and pulsar+ssl://) connections with DNS lookup
• multi topic consumers (based on a regex or list)
• TLS connection
• configurable executor (Tokio or async-std)
• automatic reconnection with exponential back off
• message batching
• compression with LZ4, zlib, zstd or Snappy (can be deactivated with Cargo features)
• telemetry using tracing crate (can be activated with Cargo features)

Getting Started

Add the following dependencies in your Cargo.toml:

toml futures = "0.3" pulsar = "4.0" tokio = "1.0"
