Struct wayland_client::protocol::wl_region::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 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 PartialEq<Weak<WlRegion>> for WlRegion

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialEq<WlRegion> for WlRegion

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Proxy for WlRegion
