Function strict_encoding_test::test_encoding_roundtrip

source · 
pub fn test_encoding_roundtrip<T, const MAX: usize>(
    object: &T,
    test_vec: Vec<u8>,
) -> Result<(), DataEncodingTestFailure<T>>
where
    T: StrictEncode + StrictDecode + PartialEq + Clone + Debug,
Expand description

Test helper performing double encode-decode roundtrip for an object and a matching binary encoding test vector. Object type must be PartialEq + Clone + Debug.

§Error

Errors on:

  • encoding or decoding failures;
  • if the original object is not equivalent to its decoded version;
  • if the original test vector is not equivalent to its transcoded version;
  • if encoder returns number of bytes that does not match the length of the test vector.

§Panics

Function does not panics and instead returns DataEncodingTestFailure for each type of test failures.

§Example

ⓘ

#[derive(Clone, PartialEq, Eq, Debug, StrictEncode, StrictDecode)]
struct Data(pub Vec<u8>);

let data = Data(vec![0x01, 0x02]);
test_encoding_roundtrip(&data, &[0x02, 0x00, 0x01, 0x02]).unwrap();
