Function register_sha512_functions 

pub fn register_sha512_functions(conn: &Connection) -> Result<()>

Register the sha512 SQL function with the given SQLite connection. The function takes a single argument and returns the SHA512 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_sha512_functions(&db)?;
let hash: Vec<u8> = db.query_row("SELECT sha512('hello')", [], |r| r.get(0))?;
let expected = b"\x9b\x71\xd2\x24\xbd\x62\xf3\x78\x5d\x96\xd4\x6a\xd3\xea\x3d\x73\x31\x9b\xfb\xc2\x89\x0c\xaa\xda\xe2\xdf\xf7\x25\x19\x67\x3c\xa7\x23\x23\xc3\xd9\x9b\xa5\xc1\x1d\x7c\x7a\xcc\x6e\x14\xb8\xc5\xda\x0c\x46\x63\x47\x5c\x2e\x5c\x3a\xde\xf4\x6f\x73\xbc\xde\xc0\x43";
