Overview

A near-lock-free structured logging library for Rust, built as a 10-crate workspace. It achieves sub-microsecond ingest through a 65k-slot ring buffer inspired by the LMAX Disruptor. The workspace includes components such as an MCP server for Claude/Cursor, OTLP exporters, Tower middleware, WASM/WASI support, eBPF-style enrichers, PII redaction, log analytics, test utilities, and a jq-style CLI.

Use cases

• Instrument Rust applications with high-performance structured logging
• Export logs via OTLP HTTP/gRPC to OpenTelemetry collectors
• Redact PII from log output at the source

Pros

• Sub-microsecond ingest latency due to ring buffer design
• Rich ecosystem of components including MCP server and Tower middleware
• Supports WASM/WASI for cross-platform deployment

Cons

• Small community with only 4 GitHub stars, indicating limited adoption
• Requires Rust ecosystem; not suitable for non-Rust projects
• Complex workspace with 10 crates may have a steep learning curve
