derived-deref

一个用于从具有至少一个字段的struct派生标准库中的Deref和DerefMut特质的Crate。具有引用的字段将直接传递。

示例

use derived_deref::{Deref, DerefMut};

#[derive(Deref, DerefMut)]
struct StringWithCount {
    // Annotation of `#[target]` is required when there are two+ fields.
    #[target] inner: String,
    count: usize,
}


// When there is only one field, annotation is optional instead.

#[derive(Deref, DerefMut)]
struct StringWrapper(String);

#[derive(Deref, DerefMut)]
struct CountWrapper(#[target] usize);
