  E0519   the current crate is indistinguishable from one of its  dependencies: it has the same crate-name {} and was compiled with the same -C metadata arguments. This will result in symbol conflicts between the two.  local crate and dependency have same (crate-name, disambiguator)
  E0521   redundant default implementations of trait
