#[repr(transparent)]
pub struct LParam(pub LPARAM);

Newtype wrapper for LPARAM with utility methods.

Tuple Fields

0: LPARAM

Implementations

impl LParam

pub const fn new(value: isize) -> Self

Creates a new LPARAM wrapper.

pub const fn raw(&self) -> LPARAM

Returns the raw value.

pub const fn as_isize(&self) -> isize

Returns the inner isize value.

pub fn as_u32(&self) -> u32

Converts to u32 (truncating on 64-bit platforms).

pub fn as_i32(&self) -> i32

Converts to i32 (truncating on 64-bit platforms).

pub fn as_point(&self) -> (i16, i16)

Extracts coordinates from LPARAM (for mouse messages).

pub fn from_point(x: i16, y: i16) -> Self

Creates LPARAM from coordinates.

Trait Implementations

impl Clone for LParam

fn clone(&self) -> LParam

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LParam

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

Formats the value using the given formatter.

impl Default for LParam

fn default() -> LParam

Returns the “default value” for a type.

impl Display for LParam

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

Formats the value using the given formatter.

impl From<LParam> for isize

fn from(lparam: LParam) -> Self

Converts to this type from the input type.

impl From<isize> for LParam

fn from(value: isize) -> Self

Converts to this type from the input type.

impl Hash for LParam

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 PartialEq for LParam

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