Struct key_native::Class

pub struct Class { /* private fields */ }

原生类型指针

Implementations

impl Class

pub const fn uninit() -> Self

为static创建一个空指针

要在此后调用其new方法才能访问

pub fn new(&self, name: &str)

为Class内部创建一个新类

重复调用会引起一个ClassInner的内存泄漏

pub fn create(&self, v: usize, w: usize) -> Litr

为此类创建一个实例

v是两个指针长度的内容，可以传任何东西然后as或者transmute

pub fn getter(&self, f: fn(_: &Instance, get: Ident) -> Litr)

设置getter, 用来处理.运算符

pub fn setter(&self, f: fn(_: &mut Instance, set: Ident, to: Litr))

设置setter, 用来处理a.b = c的写法

pub fn index_get(&self, f: fn(_: &Instance, _: LitrRef) -> Litr)

设置index getter, 返回a[i]的值

pub fn index_set(&self, f: fn(_: &mut Instance, _: LitrRef, _: LitrRef))

设置index setter, 处理a[i] = b

pub fn next(&self, f: fn(_: &mut Instance) -> Litr)

设置迭代器, 处理for n:instance {}

pub fn onclone(&self, f: fn(_: &Instance) -> Instance)

自定义复制行为(往往是赋值和传参)

pub fn ondrop(&self, f: fn(_: &mut Instance))

自定义垃圾回收回收行为(只需要写额外工作,不需要drop此指针)

pub fn to_str(&self, f: fn(_: &Instance) -> String)

自定义Str::from得到的字符串

pub fn method(&self, name: &str, f: NativeMethod)

添加一个方法

pub fn static_method(&self, name: &str, f: NativeFn)

添加一个静态方法
