fit_file

FIT file parser written in Rust. FIT (Flexible and Interoperable Data Transfer) is a binary file format that is commonly used to exchange fitness data, such as that from a sports watch or bike computer.

Example

```rust extern crate fit;

use std::io::BufReader; use std::fs::File;

/// Called for each record message as it is processed. fn callback(timestamp: u32, globalmessagenum: u16, localmsgtype: u8, fields: Vec) { if globalmessagenum == crate::fit::GLOBALMSGNUMSESSION { let msg = crate::fit::FitSessionMsg::new(fields); let sportnames = crate::fit::initsportnamemap(); let sportid = msg.sport.unwrap();

    println!("Sport: {}", sport_names.get(&sport_id).unwrap());
}
else if global_message_num == crate::fit::GLOBAL_MSG_NUM_RECORD {
    let msg = crate::fit::FitRecordMsg::new(fields);

    println!("Timestamp: {} Latitude: {} Longitude: {}", timestamp, crate::fit::semicircles_to_degrees(msg.position_lat.unwrap()), crate::fit::semicircles_to_degrees(msg.position_long.unwrap()));
}

}

fn main() { let file = std::fs::File::open("tests/20210218_zwift.fit").unwrap(); let mut reader = std::io::BufReader::new(file); let fit = crate::fit::read(&mut reader, callback); } ```

Current Status

Work in progress.
