Rust早就实现自举了，编译器是用Rust写的，发帖之前了解一下哈

Notes
Since the Rust compiler is written in Rust, it must be built by a precompiled "snapshot" version of itself (made in an earlier stage of development). As such, source builds require a connection to the Internet, to fetch snapshots, and an OS that can execute the available snapshot binaries.

: rust不是使用的C++编译器嘛？
: 如果rust免费，C++收费，那用户使用rust还是得掏钱啊（假设没dao版可用的话）
