A hashmap for Rust that uses case-insensitive strings as keys.
rust
let mut map = CaseInsensitiveHashMap::<u8>::new();
map.insert("A", 1);
assert!(map.contains_key("A"));
assert!(map.contains_key("a"));
assert!(!map.contains_key("B"));
assert!(!map.contains_key("Å"));
The API is identical to the HashMap
in std.
This use the UniCase crate to handle
the case-insensitivity. Strings that are used as keys are wrapped in
UniCase objects so that they hash and compare for equality in a
case-insensitive manner.
