The problem I met is the following. A trait
algebra::ToBytes is not implemented for
[u8; 65536] in the lib I use. When I try to implement it, I succeed to implement a trait
bytes::ToBytes for type
[u8; 65536] by using a macro. But I still got the message trait
algebra::ToBytes is missing, in the end.
The trait with the name ToBytes is defined only once in the lib, it is done in the file I edit.
Have you any suggestions?
