zerotrie

A data structure offering zero-copy storage and retrieval of byte strings, with a focus on the efficient storage of ASCII strings. Strings are mapped to usize values.

[ZeroTrie] does not support mutation because doing so would require recomputing the entire data structure. Instead, it supports conversion to and from LiteMap and BTreeMap.

There are multiple variants of [ZeroTrie] optimized for different use cases.

Examples

use zerotrie::ZeroTrie;

let data: &[(&str, usize)] = &[("abc", 11), ("xyz", 22), ("axyb", 33)];

let trie: ZeroTrie<Vec<u8>> = data.iter().copied().collect();

assert_eq!(trie.get("axyb"), Some(33));
assert_eq!(trie.byte_len(), 18);
