## 依赖

```shell
cargo add base64 -p error-code
cargo add axum --features http2 --features query --features tracing --dev -p error-code
cargo add tokio --features rt --features rt-multi-thread --features macros --dev -p error-code
cargo add tracing --dev -p error-code
cargo add tracing-subscriber --features env-filter --dev -p error-code
# 堆栈信息

cargo add darling -p error-code-derive
cargo add proc-macro2 -p error-code-derive
cargo add quote -p error-code-derive
cargo add syn --features extra-traits -p error-code-derive
```


## 创建 workspace
```shell
cargo new error-code
cargo new error-code-derive
rm -rf src/
```

修改 cargo.toml
```toml
[workspace]
members = [
    "error-code",
    "error-code-derive",
]
# 写成聚合的形式，否则就需要写成类似 properties 的样式
resolver= "2"


[workspace.dependencies]
# 可以在 workspace 内部，引入crate时，很方便
error-code = { path = "../error-code" }
error-code-derive = { path = "../error-code-derive" }
```


## 宏展开查看
```shell
cd error-code
cargo expand --example error
```

## test
```shell
cd error-code
cargo nextest run -- test_data_struct --nocapture
```
