provenance 0.1.0

Container structures that generate key upon insertion that only works with the map that generated it.


A Rust library that provides containers that upon insertion generate a key. This key will only work with the map that generated it.

Using the library

Add the following to your Cargo.toml:

provenance = "0.1.0"


use provenance::ProvenanceMap;

fn main() {
    let ages = ProvenanceMap::<u32>::new().unwrap();
    let names = ProvenanceMap::<String>::new().unwrap();
    let middle_age: Key<u32> = ages.insert(40); // Key generated on insert
    assert_eq!(&40, ages.get(middle_age)); // Key is used to retrieve stored value
    // names.get(middle_age); // Compile error, key can only be used with it's map
