Struct WlRegion

pub struct WlRegion { /* private fields */ }

region interface

A region object describes an area.

Region objects are used to describe the opaque and input regions of a surface.

This interface has no events.

Implementations

impl WlRegion

pub fn destroy(&self)

destroy region

Destroy the region. This will invalidate the object ID.

pub fn add(&self, x: i32, y: i32, width: i32, height: i32)

add rectangle to region

Add the specified rectangle to the region.

pub fn subtract(&self, x: i32, y: i32, width: i32, height: i32)

subtract rectangle from region

Subtract the specified rectangle from the region.

Trait Implementations

impl Borrow<ObjectId> for WlRegion

fn borrow(&self) -> &ObjectId

Immutably borrows from an owned value.

impl Clone for WlRegion

fn clone(&self) -> WlRegion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WlRegion

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

Formats the value using the given formatter.

impl Hash for WlRegion

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<Weak<WlRegion>> for WlRegion

fn eq(&self, other: &Weak<WlRegion>) -> 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 PartialEq for WlRegion

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