Struct WindowsHook 

pub struct WindowsHook { /* private fields */ }

Windows 的钩子。

Implementations

impl WindowsHook

pub fn next_hook( self, w_param: WPARAM, l_param: LPARAM, ) -> Result<LRESULT, WindowsHookError>

调用钩子链中下一个函数

pub fn new<F>(hook_type: HookType, cb: F) -> Result<Self, WindowsHookError>

where F: FnMut(WindowsHook, WPARAM, LPARAM) -> Result<LRESULT, WindowsHookError> + Send + Sync + 'static,

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::{WindowsHookError,WindowsHook}};
fn cb(hook: WindowsHook, w_param: WPARAM, l_param: LPARAM) -> Result<LRESULT, WindowsHookError> {hook.next_hook(w_param,l_param)}

也可以使用闭包

use win_wrap::{common::{LPARAM, WPARAM}, hook::{WindowsHookError,WindowsHook}};
|hook: WindowsHook, w_param: WPARAM, l_param: LPARAM| {hook.next_hook(w_param,l_param)};

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

pub fn unhook(&self) -> Result<(), WindowsHookError>

卸载钩子。

Trait Implementations

impl Clone for WindowsHook

fn clone(&self) -> WindowsHook

Returns a duplicate 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.
