Function check_decode 

pub fn check_decode<T: Decode + Eq + Debug>(bytes: &[u8], expected: &T)
where
    <T::Decoder as Decoder>::Error: Debug,

Checks that the given bytes decode to the expected consensus decodable value, panicking if they don’t.

This is intended for tests only.

Panics

If the decoded value doesn’t match the expected value, or if decoding fails.
