Function wafer::input::read_csv

fn read_csv(
    file: &str, 
    target_size: [usize; 3], 
    bb: usize, 
    log: &Logger
) -> Result<Array3<R64>, Error>

Given a filename, this function reads in the data of a csv file and parses the values into a 3D array. There are a few caveats to this as the file may be of a different shape to the requested size in the configuration file. The routine therefore attempts to resample/interpolate the data to fit the required parameters.

Arguments

• file - A filename wrapped in an option. This function is called from filename parsers which may not be able to obtain a valid location.
• target_size - Requested size of the resultant array. If this size does not match the data pulled from the file, interpolation or resampling will occur.

Returns

• A 3D array loaded with data from the file and resampled/interpolated if required. If something goes wrong in the parsing or file handling, a csv::Error is passed.
