vim-racer conflicting with neocomplete?

[Shougo]

Hm.

I want to test the behavior.
Please create the minimal vimrc and the reproduce ways from Vim starting.

Here's a minimal vimrc that reproduces the error for me:

set nocompatible

if empty(glob('~/.vim/autoload/plug.vim'))
  silent !curl -fLo ~/.vim/autoload/plug.vim --create-dirs
    \ https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
  autocmd VimEnter * PlugInstall --sync | source $MYVIMRC
endif

call plug#begin('~/.vim/bundle')
Plug 'Shougo/neocomplete.vim'
Plug 'racer-rust/vim-racer'
call plug#end()

let g:neocomplete#enable_at_startup = 1

Obviously you can replace the vim-plug part with any other method to get the plugs installed.

A test file (save as ./src/main.rs):

fn main() {
    println!("Hello, world!");
}

The error appears for me when I try to insert .unwrap() between the ) and the ;. (Note, .unwrap() is not a valid method at that point, but it still shouldn't mangle the input.)

Vim version is 8.0.0851.

I will test it.

I think your machine is very slow and the input is lost.
You can test it in another machine.

I doubt speed is the problem. i5-3550, 16G, data on SSD and there's almost no load.

Even if I type really slowly the changes happen and you can see the cursor jumping back and forth.

[Shougo]

Reproduced.
It is racer completion is too slow problem.
I cannot fix it.
You should use deoplete instead.

I might look into that, but I'm not yet on NeoVim. For now, YCM works for rust.

For now, YCM works for rust.

YCM has own integration with racer.
So it has not the problem.
