Rust Logging Libraries

This project is a structured tracing framework for Rust that serves as an async-aware instrumentation library and telemetry data collector. It provides a structured logging facade and the tools necessary to record, filter, and route event-based diagnostic data from both standard applications and embedded systems. The framework distinguishes itself through a core implementation that supports bare-metal and no-standard-library environments without requiring a dynamic memory allocator. It specifically handles the complexities of asynchronous workflows by propagating diagnostic contexts across fu

This project provides a lightweight logging facade for Rust applications, serving as a standardized interface for recording diagnostic messages. By decoupling application code from specific logging backends, it allows developers to maintain a consistent diagnostic surface while remaining independent of the underlying implementation. The framework enables the attachment of structured key-value metadata to log records, providing additional context that facilitates more granular filtering and analysis of application events. Its core design is built to be minimal, ensuring compatibility with reso
