Lib.rs

Getset，我们准备好了！

一个用于生成字段最基本的获取器和设置器的进程宏。

获取器生成为 fn field(&self) -> &type，而设置器生成为 fn field(&mut self, val: type)。

这些宏不打算用于需要在其设置器和获取器内部进行自定义逻辑的字段。在这种情况下，请自己编写！

#[macro_use]
extern crate getset;

#[derive(Getters, Setters, New, Default)]
#[get(vis = "pub")]
#[get(vis = "pub", mutable)]
#[set(vis = "pub", consume)]
#[set(vis = "pub")]
#[new(vis = "pub")]
pub struct Foo<T> where T: Copy + Clone + Default {
/// Doc comments are supported!
/// Multiline, even.
#[get(copy)] #[get(mutable)] #[set]
private: T,

/// Doc comments are supported!
/// Multiline, even.
public: Option<T>,

#[set(optional)]
optional: Option<String>,
}

fn main() {
let mut foo: Foo<i64> = Foo::new(1).consume_set_public(3);
assert_eq!(foo.private(), 1);
assert_eq!(*foo.public(), Some(3));
foo.set_private(3);

foo.set_optional(None::<&str>);
assert_eq!(*foo.optional(), None);
}
