tdms's Issues

Implement asynchronously reading TDMS files using `tokio::fs`

Asynchronously reading large TDMS files using tokio::fs could be beneficial for performance. I am willing to create a pull request for this and draw on my experience from implementing reading TDMS files in F#.

TDMSValue from_path method do not exist

Hi,

I am starting with rust and labview and I am trying out this library, thanks for the work men!

Just a question about how to extract a value from a TDMSValue. In this particular case I need to extract the date to send it to a .csv file. I have this function:

fn extract_date(tdms_file: &TDMSFile, file: &mut File) -> std::io::Result<()> {
    let name = tdms_file.segments.get(0).unwrap().metadata.clone().unwrap();
    let obj = name
        .objects
        .iter()
        .find(|obj| obj.object_path == "/")
        .unwrap();
    // .collect();
    let date = obj
        .properties
        .iter()
        .find(|n| n.name == "DateTime")
        .unwrap()
        .value
        .clone();
    println!("extract date ---------->>> {:?}", date);
    Ok(())
}

date is of type TDMSValue, reading the docs I found that this struct has a method pub fn from_reader(...)
that I supose that is to extract that value from value depending on each type, but It seems that this function does not exists. I am not able to call this function.

Do you know what can be happening? any help is welcome. 😃

Reading file in causes 'index out of bounds' error

I am attempting to read in a tdms file so I can perform calculations on the data contained within. The structure of the file is this:

test.tdms
    aux_data
        time [s] 
        distance [in]
        gps 
    mic_data
        time [s]
        mic 1
        mic 2 
        ... mic 12

Reading in this test.tdms file like so:

let file = match TDMSFile::from_path(Path::new("src/data/test.tdms")) {
        Ok(f) => f,
        Err(e) => panic!("{:?}", e),
    };

throws the following error. I fear that the error is due to the tiered structure of my data because reading in the provided (non-tiered) standard, raw, and big endian tdms files works fine.
