# xboot
## English Readme
With the help of [linkme](https://github.com/dtolnay/linkme), call an asynchronous function to initialize static variables.
You can connect to the database before the program starts and set it as a module-level variable, refer to [xkv: redis global connector](https://crates.io/crates/xkv).
linkme will report an error when linking with `rust-lld` on Linux [Missing symbol on Linux](https://github.com/dtolnay/linkme/issues/107).
Please use [mold](https://github.com/rui314/mold) instead, and configure the environment variables as follows:
```
export RUSTFLAGS="$RUSTFLAGS -C linker=clang -C link-arg=-fuse-ld=/usr/bin/mold"
```
## 中文说明
借助 [linkme](https://github.com/dtolnay/linkme)，调用异步函数初始化静态变量。
可在程序启动之前连上数据库，并设置为一个模块级别的变量，参考 [xkv: redis 全局连接器](https://crates.io/crates/xkv) 。
linkme 在 Linux 上用 `rust-lld` 链接会报错 [Missing symbol on Linux](https://github.com/dtolnay/linkme/issues/107)
请改用 [mold](https://github.com/rui314/mold) ，配置环境变量如下:
```
export RUSTFLAGS="$RUSTFLAGS -C linker=clang -C link-arg=-fuse-ld=/usr/bin/mold"
```
