Start by tracing how the Syntastic cargo checker invokes Cargo from rust.vim; the report identifies the checker as cargo and says linting blocks Vim while holding the build directory lock. Check the lint invocation and any related tests for synchronous process handling. Done means linting no longer freezes Vim or blocks other Cargo commands while it runs.

描述

Hi, when i run a syntastic lint while this plugin is installed, vim gets blocked for multiple seconds.
Apparently i am unable to run any other cargo commands while the lint is going on aswell since this plugin seems to lock the directory.

Output from other cargo commands while linting

    Blocking waiting for file lock on build directory
  • rust.vim version: Vim Plug and rust.vim@4aa69b84c8a58fcec6b6dad6fe244b916b1cf830

Steps to reproduce:

  1. Use Vim Plug, Syntastic and rust.vim together
  2. Open any rust project
  3. Run a syntastic lint

Expected vs. actual behavior:

rust.vim shouldnt lock my working directory and shouldnt freeze vim.
it should run asynchronously in the background
