Function pact_matching_ffi::models::message::message_find_metadata

#[no_mangle]
pub extern "C" fn message_find_metadata(
    message: *const Message, 
    key: *const c_char
) -> *const c_char

Get a copy of the metadata value indexed by key.

Safety

The returned string must be deleted with string_delete.

Since it is a copy, the returned string may safely outlive the Message.

The returned pointer will be NULL if the metadata does not contain the given key, or if an error occurred.

Error Handling

On failure, this function will return a NULL pointer.

This function may fail if the provided key string contains invalid UTF-8, or if the Rust string contains embedded null (‘\0’) bytes.
