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 FIT SDK for Go and is designed to run on baremetal Rust.

Current State

At the moment, I can't make this library heapless without complicating the code. I have no elegant solution for pure baremetal without dynamic memory allocation. That being said, this library is efficient enough to work on resource-constrained environments. I've tested it on a #![no_std] program to decode a FIT file (statically embedded) and print some of its Session's fields to stdout with a custom global allocator having less than 50 KB heap size and it works like a charm.

Usage

For #![no_std], you need to provide #[global_allocator] since this library requires allocation.

For std, you need to wrap std::io's Read or Write with embedded_io_adapters::std:FromStd.

Usage examples can be viewed on docs.rs.
