I am not the Rust translator but fixed. Thanks!

Wrong function signature for Rust version. Instead fn dir_reduc(arr: &[&'static str]) -> Vec<&'static str> should be fn dir_reduc(arr: &[Direction]) -> Vec<Direction> in "Initial solution" tab.

Hello, please add rand crate for Rust lang. Rust does not have rand function in std library. It's need for translating kata when writing tests.
