pub fn hmac(t: Type, key: &[u8], data: &[u8]) -> Vec<u8>
Computes the HMAC of the data with the hash t and key.
Prefix searches with a type followed by a colon (e.g.
fn:) to restrict the search to a given type.
Accepted types are: fn, mod,
struct, enum,
trait, typedef (or
tdef).
Search functions by type signature (e.g.
vec -> usize)
