Fields

page_id: usize

Page ID that needs updating.

x: u32

X coordinate of the region.

y: u32

Y coordinate of the region.

width: u32

Implementations

impl UpdateRegion

pub fn empty() -> Self

Create an empty update region.

pub fn is_empty(&self) -> bool

Check if this region is empty.

pub fn area(&self) -> u64

Get the area of this region in pixels.

Trait Implementations

impl Clone for UpdateRegion

fn clone(&self) -> UpdateRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UpdateRegion

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

Formats the value using the given formatter.

impl PartialEq for UpdateRegion

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