RLS or neovim/vim

[DevinBayly]

Hi there,
I would like to know whether you believe missing completion items to be from the RLS side or something in the neovim/vim side.
my main.rs file looks like this

use std::rc::{Rc,Weak};

fn my_func() {}

fn main() {
    let A = Rc::new(50);
    let B = Rc::clone(&A);
    println!("{:?} {:?}",B,A);
}

When finishing the line defining B i don't see clone in the completion options for Rc::
the second thing is a list of completions can be seen when typing A. but not B.

I have an init.vim

filetype plugin indent on 
"" the junegun plugged section
call plug#begin('~/.local/share/nvim/plugged')
Plug 'rust-lang/rust.vim'
Plug 'autozimu/LanguageClient-neovim', {
    \ 'branch': 'next',
    \ 'do': 'bash install.sh',
    \ }
Plug 'sebastianmarkow/deoplete-rust'

if has('nvim')
  Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
else
  Plug 'Shougo/deoplete.nvim'
  Plug 'roxma/nvim-yarp'
  Plug 'roxma/vim-hug-neovim-rpc'
endif
call plug#end()
let g:deoplete#sources#rust#racer_binary='~/.cargo/bin/racer'
let g:deoplete#sources#rust#rust_source_path='~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu'
" Required for operations modifying multiple buffers like rename.
set hidden

let g:deoplete#enable_at_startup = 1

Let me know if you have any ideas about this.
