tdms

tdms is a LabVIEW TDMS file parser library written in Rust. This is meant to be a general purpose library for reading and performing any calculation work on data contained in those files.

Note: This library is a work in progress. While I do not expect the current function signatures and library structure to change, you could experience difficulties due to early adoption.

Current Features

• Read both standard and big endian encoded files
• Read files with DAQmx data and data indices
• Read all segments in file, along with their groups and channels (per segment only)
• Read all raw data contained in all segments in file (as a Vec<u8> only at the present time)

Usage

```rust extern crate tdms;

use std::path::Path; use tdms::TDMSFile;

fn main() { // open and parse the TDMS file, passing in metadata false will mean the entire file is // read into memory, not just the metadata let file = match TDMSFile::from_path(Path::new("data/standard.tdms"), false) { Ok(f) => f, Err(e) => panic!("{:?}", e), };

// fetch groups
let groups = file.groups();

for group in groups {
    // fetch an IndexSet of the group's channels
    let channels = file.channels(&group);

    for channel in channels {
        // once you know the channel's full path (group + channel) you can ask for the full
        // channel object. This contains all the segments that contain this data channel
        // eventually this will also implement Iterator, allowing you to iterate through
        // the channels raw data, currently planned
        match file.channel(&group, &channel) {
            Ok(c) => c,
            Err(e) => panic!("{:?}", e),
        };
    }
}

} ```
