Zig 标准库:

std 文档:

• ✅ https://ziglang.org/documentation/master/std/
  • Zig 1.0版本还未发布, 所以, 请直接根据 master 的 dev 版本学习.
  • 因为第三方库, 可能大多数是基于 dev 版本的. 使用新特性.
  • 这个网站, 加载有点慢, 耐心等待.
• ✅ https://ziglang.org/documentation/master/

std 源码:

• ✅ https://github.com/ziglang/zig/tree/master/lib/std
• ✅ https://github.com/ziglang/zig

官方对 std 源码阅读建议:
