Trait Implementations

impl Debug for HHOOK

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

Formats the value using the given formatter.

impl Display for HHOOK

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

Formats the value using the given formatter.

impl Handle for HHOOK

const NULL: Self

Available on crate feature kernel only.

The null, uninitialized handle; equals to 0.

const INVALID: Self

Available on crate feature kernel only.

The invalid handle; equals to -1.

unsafe fn from_ptr(p: *mut c_void) -> Self

Available on crate feature kernel only.

Creates a new handle object by wrapping a pointer.

unsafe fn as_mut(&mut self) -> &mut *mut c_void

Available on crate feature kernel only.

Returns a mutable reference to the underlying raw pointer.

unsafe fn raw_copy(&self) -> Self

Available on crate feature kernel only.

Returns a raw copy of the underlying handle pointer.

fn ptr(&self) -> *mut c_void

Available on crate feature kernel only.

Returns the underlying raw pointer.

fn as_opt(&self) -> Option<&Self>

Available on crate feature kernel only.

Returns None if the handle is null or invalid, otherwise returns Some(&self).

impl Hash for HHOOK

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl LowerHex for HHOOK

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

Formats the value using the given formatter.

impl PartialEq for HHOOK

fn eq(&self, other: &HHOOK) -> 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.

impl UpperHex for HHOOK

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

Formats the value using the given formatter.

impl user_Hhook for HHOOK

fn CallNextHookEx(&self, code: WH, wparam: usize, lparam: isize) -> isize

CallNextHookEx function.

fn SetWindowsHookEx( hook_id: WH, proc: HOOKPROC, module: Option<&HINSTANCE>, thread_id: Option<u32>, ) -> SysResult<HHOOK>

SetWindowsHookEx function.

fn UnhookWindowsHookEx(&mut self) -> SysResult<()>

UnhookWindowsHookEx function.
