Crate hashmatch 

More efficient static &str matching when match #arm > 30.

use hashmatch::{hash_arm, hash_str};
// to avoid hash conflict
#[deny(unreachable_patterns)]
let res = match hash_str("ABC") {
    hash_arm!("ABC") => 1,
    hash_arm!("AAA") | hash_arm!("BBB") => 2,
    _ => 3,
};
assert_eq!(res, 1);

Macros

hash_arm

Obtain hash of literals (&’static str)

Functions

hash_str

Runtime hash with consistency of hash_arm! (hash_arm! is compling time)
