Struct Region 

pub struct Region<U: Unsigned + Copy = u16> { /* private fields */ }

A square region defined by a bottom-left point and a size, in integer units.

Implementations

impl<U: Unsigned + NumCast + Copy> Region<U>

pub fn new(x: U, y: U, size: U) -> Self

Create a new region with the given bottom-left point coordinates and size.

pub fn x(&self) -> U

Get the x component of the bottom-left point.

pub fn y(&self) -> U

Get the y component of the bottom-left point.

pub fn point(&self) -> UVec2

Get the bottom-left point.

pub fn end_point(&self) -> UVec2

Get the top-right point.

pub fn center(&self) -> UVec2

Get the center point.

pub fn size(&self) -> U

Get the size of the region.

pub fn size_as<N: NumCast>(&self) -> N

pub fn half_size(&self) -> U

Get the region size / 2.

pub fn is_unit(&self, pixel_size: u8) -> bool

Determine if this region represents the smallest possible unit or pixel size.

pub fn contains_upoint<P>(&self, point: P) -> bool

where P: Into<UVec2>,

Determine if the given point is contained within this region.

pub fn contains_ipoint<P>(&self, point: P) -> bool

where P: Into<IVec2>,

Determine if the given point is contained within this region.

pub fn quadrant_for_upoint<P>(&self, point: P) -> Quadrant

where P: Into<UVec2>,

Obtain the quadrant for the given point in relation to the center of this region.

pub fn quadrant_for_ipoint<P>(&self, point: P) -> Quadrant

where P: Into<IVec2>,

Obtain the quadrant for the given point in relation to the center of this region.

pub fn intersect(&self, other: &URect) -> URect

pub fn as_urect(&self) -> URect

Trait Implementations

impl<U: Clone + Unsigned + Copy> Clone for Region<U>

fn clone(&self) -> Region<U>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<U: Debug + Unsigned + Copy> Debug for Region<U>

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

Formats the value using the given formatter.

impl<U: Hash + Unsigned + Copy> Hash for Region<U>

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<U: Unsigned + NumCast + Copy> Into<IRect> for &Region<U>

fn into(self) -> IRect

Converts this type into the (usually inferred) input type.

impl<U: Unsigned + NumCast + Copy> Into<IRect> for Region<U>

fn into(self) -> IRect

Converts this type into the (usually inferred) input type.

impl<U: Unsigned + NumCast + Copy> Into<URect> for &Region<U>

fn into(self) -> URect

Converts this type into the (usually inferred) input type.

impl<U: Unsigned + NumCast + Copy> Into<URect> for Region<U>

fn into(self) -> URect

impl<U: PartialEq + Unsigned + Copy> PartialEq for Region<U>

fn eq(&self, other: &Region<U>) -> 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.
