Struct win_wrap::hook::WindowsHook

pub struct WindowsHook(/* private fields */);

Windows 的钩子。

Implementations

impl WindowsHook

pub fn new( hook_type: HookType, cb: impl Fn(&WPARAM, &LPARAM, &NextHookFunc) -> LRESULT + Sync + Send + 'static, ) -> Self

创建一个钩子对象并开始监听事件。 hook_type 钩子类型，使用“HOOK_TYPE_”开头的常亮。 cb 用于接收事件的处理函数，需要实现三个参数：

use win_wrap::{common::{LPARAM, WPARAM, LRESULT}, hook::NextHookFunc};
fn cb(w_param: &WPARAM, l_param: &LPARAM, next: &NextHookFunc) -> LRESULT {next()}

也可以使用闭包

use win_wrap::{common::{LPARAM, WPARAM}, hook::NextHookFunc};
|w_param: &WPARAM, l_param: &LPARAM, next: &NextHookFunc| {next()};

处理函数运行在单独的子线程中，使用时可以通过next()调用钩子链中的下一个函数，也可以直接拦截。

pub fn unhook(&self)

卸载钩子。

Trait Implementations

impl Clone for WindowsHook

fn clone(&self) -> WindowsHook

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WindowsHook

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for WindowsHook

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
