Fitparse

Fitparse is a Rust library which implements a parser for Garmin's FIT file format.

Capabilities

• Implments most of the FIT standard, including:
  • Basic parsing of Definition and Data messages
  • Developer Fields
  • Unknown (i.e., not in FIT profile) fields
  • Subfields
  • Components
• Not yet supported:
  • Accumulators
  • Chained FIT files
  • File CRC verification

Example

use fitparse::fitfile::FitFile;

let mut f = match File::open("/path/to/fit_file.fit").unwrap(); 

let mut fit_file = FitFile::new(
    1024 * 1024 * 10, // maximum file size, here 10 Mb
    true              // retain the raw bytes for per-message inspection
);

match ff.parse(&mut f) {
    Err(e) => panic!("failed to parse file: {:?}", e),
    _ => (),
}

println!("Parsed num messages: {}", ff.messages.len());

println!("Message #42:");
println!("{}", ff.messages[42]);
