Function register_blake3_functions 

pub fn register_blake3_functions(conn: &Connection) -> Result<()>

Register the blake3 SQL function with the given SQLite connection. The function takes a single argument and returns the BLAKE3 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_blake3_functions(&db)?;
let hash: Vec<u8> = db.query_row("SELECT blake3('hello')", [], |r| r.get(0))?;
let expected = b"\xea\x8f\x16\x3d\xb3\x86\x82\x92\x5e\x44\x91\xc5\xe5\x8d\x4b\xb3\x50\x6e\xf8\xc1\x4e\xb7\x8a\x86\xe9\x08\xc5\x62\x4a\x67\x20\x0f";
assert_eq!(hash, expected);
