Function pact_ffi::matching::pactffi_matches_binary_value

#[no_mangle]
pub extern "C" fn pactffi_matches_binary_value(
    matching_rule: *const MatchingRule,
    expected_value: *const c_uchar,
    expected_value_len: usize,
    actual_value: *const c_uchar,
    actual_value_len: usize,
    cascaded: u8
) -> *const c_char

Determines if the binary value matches the given matching rule. If the value matches OK, will return a NULL pointer. If the value does not match, will return a error message as a NULL terminated string. The error message pointer will need to be deleted with the pactffi_string_delete function once it is no longer required.

• matching_rule - pointer to a matching rule
• expected_value - value we expect to get
• expected_value_len - length of the expected value bytes
• actual_value - value to match
• actual_value_len - length of the actual value bytes
• cascaded - if the matching rule has been cascaded from a parent. 0 == false, 1 == true

Safety

The matching rule, expected value and actual value pointers must be a valid pointers. expected_value_len and actual_value_len must contain the number of bytes that the value pointers point to. Passing invalid lengths can lead to undefined behaviour.
