### Generating a Trie Root Hash

Source: https://docs.rs/triehash/0.8.4/triehash/fn.ordered_trie_root.html?search=u32+-%3E+bool

Example usage of ordered_trie_root with the KeccakHasher to compute the root hash of a slice of strings.

```rust
use hex_literal::hex;
use ethereum_types::H256;
use triehash::ordered_trie_root;
use keccak_hasher::KeccakHasher;

let v = &["doe", "reindeer"];
let root = H256::from(hex!("e766d5d51b89dc39d981b41bda63248d7abce4f0225eefd023792a540bcffee3"));
assert_eq!(ordered_trie_root::<KeccakHasher, _>(v), root.as_ref());
```

### Generating a secure trie root

Example usage of sec_trie_root with KeccakHasher to compute a trie root from a vector of key-value tuples.

```rust
use hex_literal::hex;
use ethereum_types::H256;
use triehash::sec_trie_root;
use keccak_hasher::KeccakHasher;

let v = vec![
	("doe", "reindeer"),
	("dog", "puppy"),
	("dogglesworth", "cat"),
];

let root = H256::from(hex!("d4cd937e4a4368d7931a9cf51686b7e10abb3dce38a39000fd7902a092b64585"));
