rshim is the shim program written in rust.

There are several versions of shim:

1. the official shim.cs was written in c# and required an instantiation of a .NET command line app every time it was started therefore is slower than directly executing. And it dose not handle Ctrl+C event correctly.

2. shim.c is ok with performance and Ctrl+C event handling,but sometimes suffer memory violation (randomly exited with return code 3221226356).

3. shim.cpp didn't work on my machine, calling it with any executable result in an infinite recursion of creating subprocess until eating all memory for unknown subtle reason.

1. less probability with bug and undefined behavior.
2. properly handle variety errors.
3. friendly error message.
4. properly handle Ctrl+C events.
5. properly handle utf-8 with or without bom in shim file.

First install rust

cargo build --release

Close any running process with existed shim. then

./repshims.bat
