clangd can barely do it in practice, it does not index the whole code base, instead it builds up the index gradually, and it often failed to find function implementation, it can just find those definitions, ctags has no issues to find both. I would love to stick with clangd if it can do whatever ctags can as far as source indexing goes, it seems can not.
