Struct DeviceCopy 

pub struct DeviceCopy {
    pub x: u32,
    pub y: u32,
    pub width: u32,
    pub height: u32,
    pub dx: i32,
    pub dy: i32,
}

One planned copy within a host’s retained target, in device pixels: the source rectangle, and how far it moves.

Fields

x: u32

y: u32

width: u32

height: u32

dx: i32

dy: i32

Implementations

impl DeviceCopy

pub fn destination(&self, width: u32, height: u32) -> Option<(u32, u32)>

Where the copy lands, or None when it would leave a width × height target.

pub fn destination_rect(&self) -> Rect

Where the copy lands, as a rectangle in device pixels.

Trait Implementations

impl Clone for DeviceCopy

fn clone(&self) -> DeviceCopy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceCopy

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

Formats the value using the given formatter.

impl PartialEq for DeviceCopy

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