Near-lock-free structured logging for Rust: a 65,536-slot ring buffer, formatting deferred to a background thread, 14 output formats (JSON, ECS, GELF, OTLP, logfmt…) and native os_log/journald sinks. Plus an OTLP/HTTP exporter, an MCP server for AI agents, Tower middleware, PII redaction, WebAssembly bindings and a jq-style CLI.
This repository also configures its own agents. See what rlg tells them →
