Struct LogicalRect 

#[repr(C)]
pub struct LogicalRect {
    pub origin: LogicalPosition,
    pub size: LogicalSize,
}

An axis-aligned rectangle in logical (DPI-independent) coordinates.

Fields

origin: LogicalPosition

size: LogicalSize

Implementations

impl LogicalRect

pub const fn zero() -> Self

pub const fn new(origin: LogicalPosition, size: LogicalSize) -> Self

pub fn scale_for_dpi(&mut self, scale_factor: f32)

Scales all coordinates in-place by the given DPI scale factor.

pub fn max_x(&self) -> f32

Returns the maximum x coordinate (origin.x + width).

pub fn min_x(&self) -> f32

Returns the minimum x coordinate (origin.x).

pub fn max_y(&self) -> f32

Returns the maximum y coordinate (origin.y + height).

pub fn min_y(&self) -> f32

Returns the minimum y coordinate (origin.y).

pub fn intersects(&self, other: Self) -> bool

Returns whether this rectangle intersects with another rectangle

pub fn contains(&self, point: LogicalPosition) -> bool

Returns whether this rectangle contains the given point

pub fn hit_test(&self, other: &LogicalPosition) -> Option<LogicalPosition>

Same as contains(), but returns the (x, y) offset of the hit point

On a regular computer this function takes ~3.2ns to run

Trait Implementations

impl Clone for LogicalRect

fn clone(&self) -> LogicalRect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogicalRect

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

Formats the value using the given formatter.

impl Default for LogicalRect

fn default() -> LogicalRect

Returns the “default value” for a type.

impl Display for LogicalRect

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

Formats the value using the given formatter.

impl FromIterator<LogicalRect> for LogicalRectVec

fn from_iter<T>(iter: T) -> Self

where T: IntoIterator<Item = LogicalRect>,

Creates a value from an iterator.

impl Hash for LogicalRect

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 Ord for LogicalRect

fn cmp(&self, other: &LogicalRect) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LogicalRect

fn eq(&self, other: &LogicalRect) -> 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 PartialOrd for LogicalRect

fn partial_cmp(&self, other: &LogicalRect) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
