    環境


Mac OS X 10.10.5


NVIM 0.1.1 (compiled Jan 28 2016 12:13:02)


MacVim-KaoriYa 20160205


各種プラグイン更新済み

racerの再インストール
NeobundleUpdate

deoplete, neocomplete, vim-racer, rust.vim


Rustのsrcをgit pull


OS XがYosemiteであることを除き全て最新の物に更新しました。
症状


RustのソースをNVIM + deoplete + racerで補完している際に、深さが2以上のuseでエラーが発生する。
MacVim-KaoriYa + neocomplete + racerでは問題なく補完が行われる

use std::thread; // ok
use std::time::Duration; //Durationを打とうとするとエラー

neocompleteと共存させていますが、現状neocompleteでは補完時エラーが発生しないため、そこは省略します
