fish-shell#9512 - Rewrite it in Rust

Why Port

• Gain access to more contributors and enable easier contributions. C++ is becoming a legacy language.
• Free us from the annoyances of C++/CMake, and old toolchains.
• Ensure fish continues to be perceived as modern and relevant.
• Unlock concurrent mode (see below).

Why Rust

• Rust is a systems programming language with broad platform support, a large community, and a relatively high probability of still being relevant in a decade.
• Rust has a unique strength in its thread safety features, which is the missing piece to enable concurrent mode - see below.
• Other languages considered:
  • Java, Python and the scripting family are ruled out for startup latency and memory usage reasons.
  • Go would be an awkward fit. fork is quite the problem in Go.
  • Other system languages (D, Nim, Zig...) are too niche: fewer contributors, higher risk of the language becoming irrelevant.

感觉 Rust 现在渗透的到处都是了。。。

另外不晓得为什么这么几天过去了，都没人回帖？没人用 Fish ，还是大家都不太鸟 Rust 这门语言？
