  "account": "fastlogging-rs is a high-performance logging framework for various programming languages, developed in Rust. It offers non-blocking, asynchronous logging by performing level checks and handing messages to a channel, which is then processed by a background LoggingThread. This results in faster execution compared to built-in logging modules in other languages, such as Python's built-in logging module, Apache Log4j, and Java’s FFM and JNI.\n\nfastlogging-rs provides bindings for Python, C, C++, Go, Java (FFM and JNI), and C#. The API remains consistent across all languages, allowing for seamless migration from existing logging frameworks. Features include optional file rotation and compression, AES encryption for network logging, and automatic forwarding of log messages from subprocesses to the main process. Configuration can be done via API or configuration files in JSON, XML, or YAML formats.\n\nThe framework is written in Rust and comes with thin wrappers for each supported language. Benchmark data shows that fastlogging-rs can be up to 147× faster for writing to a file and up to 207× faster for rotating file logging compared to Python's built-in logging module. When logging millions of messages, these speed improvements can be the difference between minutes and seconds. The source code, documentation, and issue tracker are available on GitHub, and the framework is licensed under the MIT or Apache-2.0 License.",
  "summary": "Every log.info(...) call can block your hot path, serialize your threads, and slow down your I/O-bound workloads. That's why I created fastlogging-rs : a Rust-powered logging framework that is extremely fast, thread-safe, and available with a similar API in 8 different programming languages . Release, 0.9.0, is available with the following features: Initial release of the Rust core (fastlogging…",
