Function register_sha224_functions 

pub fn register_sha224_functions(conn: &Connection) -> Result<()>

Register the sha224 SQL function with the given SQLite connection. The function takes a single argument and returns the SHA224 hash (blob) of that argument. The argument can be either a string or a blob. If the argument is NULL, the result is NULL.

Example

let db = Connection::open_in_memory()?;
register_sha224_functions(&db)?;
let hash: Vec<u8> = db.query_row("SELECT sha224('hello')", [], |r| r.get(0))?;
let expected = b"\xea\x09\xae\x9c\xc6\x76\x8c\x50\xfc\xee\x90\x3e\xd0\x54\x55\x6e\x5b\xfc\x83\x47\x90\x7f\x12\x59\x8a\xa2\x41\x93";
assert_eq!(hash, expected);
