Read OpenDAP binary data with pure rust
with cargo add:
cargo add --git https://github.com/mpiannucci/readapor Cargo.toml:
[dependencies]
readap = { git = "https://github.com/mpiannucci/readap" }let attrs = parse_das_attributes(input).unwrap();This returns a HashMap containing all of the attributes and their children, within another hashmap
let units: String = attrs["time"]["units"].clone().try_into().unwrap();let dataset = DdsDataset::from_bytes(&input).unwrap();let dataset = DodsDataset::from_bytes(&input).unwrap();Then extract the data and coordinates for a given variable
let mwd = if let DataArray::Int32(mwd) = dataset.variable_data("mean_wave_dir").unwrap() {
mwd
} else {
vec![]
};
let coords = dataset.variable_coords("mean_wave_dir").unwrap();
let time_data: Vec<i32> = coords[0].1.try_into().unwrap();For concrete examples, see the parse tests
This library is an OpenDAP binary data and metadata parser. It is not a data downloader. It is a lower level tool to be used in higher level data access applications.
