Struct Square

pub struct Square { /* private fields */ }

Represents a square region in an image with a left, top coordinates and size.

Implementations

impl Square

pub fn at(x: i32, y: i32) -> Self

Creates a square at the specified coordinates with unit size.

pub fn of_size(self, value: u32) -> Self

Sets the size of the square.

pub fn from_region<T: Region>(value: T) -> Option<Self>

Creates a square from a region if it is square.

pub fn new(left: i32, top: i32, size: u32) -> Self

Creates a new square with the specified left, top coordinates and size.

pub fn size(&self) -> u32

Returns the size of the square.

Trait Implementations

impl Clone for Square

fn clone(&self) -> Square

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Square

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

Formats the value using the given formatter.

impl From<(i32, i32, u32)> for Square

fn from(value: (i32, i32, u32)) -> Self

Converts to this type from the input type.

impl From<Square> for Rect

fn from(value: Square) -> Self

Converts to this type from the input type.

impl From<Square> for Target

fn from(value: Square) -> Self

Converts to this type from the input type.

impl From<Target> for Square

fn from(value: Target) -> Self

Converts to this type from the input type.

impl PartialEq for Square

fn eq(&self, other: &Square) -> 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 Region for Square

fn left(&self) -> i32

Returns the left coordinate of the region.

fn top(&self) -> i32

Returns the top coordinate of the region.

fn width(&self) -> u32

Returns the width of the region.

fn height(&self) -> u32

Returns the height of the region.

fn is_square(&self) -> bool

Checks if the region is square.

fn right(&self) -> i32

Returns the right coordinate of the region.

fn bottom(&self) -> i32

Returns the bottom coordinate of the region.

fn contains(&self, x: i32, y: i32) -> bool

Checks if the region contains a point with coordinates (x, y).

fn center(&self) -> Point2<i32>

Returns the center point of the region.

fn top_left(&self) -> Point2<i32>

Returns the top-left corner of the region as a point.

fn square(&self) -> u32

Returns the square area of the region.
