A crate that creates cartesian product of size determined at runtime.
If the size is determined at compile time, it is better to use itertools::iproduct!.
Add dependency to your Cargo.toml.

dyn-product = "0.1"
```norun use dynproduct::DynProduct;
let data = vec![ vec!["GroupA-1", "GroupA-2", "GroupA-3"], vec!["GroupB-1", "GroupB-2"], vec!["GroupC-1", "GroupC-2", "GroupC-3", "GroupC-4"], ];
for item in DynProduct::from(&data) {
println!("{:?}", item);
}
output:
