RustyFIT

The #![no_std] Rust implementation of The Flexible and Interoperable Data Transfer (FIT) Protocol for decoding and encoding Garmin FIT files, supporting FIT Protocol V2.

This library is a rewrite of the Go implementation, https://github.com/muktihari/fit, and is designed to run on bare-metal Rust, where performance and memory efficiency are carefully considered. By being #![no_std], a wide range of environments is supported, including bare-metal systems, WebAssembly, desktop applications, and servers.

This library now supports serde, allowing users to serialize FIT data into other formats, such as JSON, and deserialize it back into FIT by enabling the serde feature.

Usage
