Crate set_trie 

Fast subset and superset queries based on tries.

use set_trie::SetTrie;

let mut employees = SetTrie::new();
employees.insert(&["accounting", "banking"], "Daniels");
employees.insert(&["accounting", "banking", "crime"], "Stevens");

assert_eq!(employees.subsets(&[&"accounting", &"banking", &"crime"]).collect::<Vec<_>>(), vec![&"Daniels", &"Stevens"]);
assert_eq!(employees.subsets(&[&"accounting", &"banking"]).collect::<Vec<_>>(), vec![&"Daniels"]);
assert_eq!(employees.supersets(&[&"accounting"]).collect::<Vec<_>>(), vec![&"Daniels", &"Stevens"]);

Structs

CreatedEntry

Indicates that the entry was created.

EntryBuilder

EntryBuilder for the entry method. Entries are lazily evaluated, thus the builder is used to provide the configuration, while the entry is already evaluated.

ExistingEntry

Indicates that the entry already exists.

SetTrie

SetTries allow for efficient subset and superset queries. Think of it as a HashMap, where you want the key to be within or containing a range.

Enums

Entry

A view into a node of a SetTrie, either created or already existing.
