|
## 1. Introduction
|
|
|
|
This library is located in `kernel/crates/unified-init`.
|
|
It provides unified initialization macros to register functions into a unified initialization list. It facilitates unified initialization.
|
|
|
|
It is important to note that the array of initializers is no_mangle, so its naming should follow the rules of `模块_初始化器` to prevent naming conflicts that could lead to unexpected errors.
|
|
|
|
## 2. Usage
|
|
|
|
```rust
|
|
use system_error::SystemError;
|
|
use unified_init::define_unified_initializer_slice;
|
|
use unified_init_macros::unified_init;
|
|
|
|
/// 初始化函数都将会被放到这个列表中
|
|
define_unified_initializer_slice!(INITIALIZER_LIST);
|
|
|
|
#[unified_init(INITIALIZER_LIST)]
|
|
fn init1() -> Result<(), SystemError> {
|
|
Ok(())
|
|
}
|
|
|
|
#[unified_init(INITIALIZER_LIST)]
|
|
fn init2() -> Result<(), SystemError> {
|
|
Ok(())
|
|
}
|
|
|
|
fn main() {
|
|
assert_eq!(INITIALIZER_LIST.len(), 2);
|
|
}
|
|
|
|
```
|
|
|
|
## 3. Development
|
|
|
|
When testing, you can write test code in `main.rs`,
|
|
and then run `cargo expand --bin unified-init-expand` in the current directory to see the code after the proc macro has been expanded.
