Implementations

impl RectF

pub fn new(x: f32, y: f32, width: f32, height: f32) -> Self

创建新的浮点矩形

pub fn from_xywh(x: f32, y: f32, width: f32, height: f32) -> Self

从 x, y, width, height 创建矩形（与 new 相同，提供兼容性）

pub fn from_ltrb(left: f32, top: f32, right: f32, bottom: f32) -> Self

从 left, top, right, bottom 创建矩形

pub fn from_point_size(point: PointF, width: f32, height: f32) -> Self

从左上角点和尺寸创建矩形

pub fn to_rect(&self) -> Rect

转换为整数矩形（四舍五入）

pub fn center(&self) -> PointF

获取中心点

Trait Implementations

impl Clone for RectF

fn clone(&self) -> RectF

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RectF

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

Formats the value using the given formatter.

impl Default for RectF

fn default() -> Self

Returns the “default value” for a type.

impl From<Rect> for RectF

fn from(r: Rect) -> Self

Converts to this type from the input type.

impl PartialEq for RectF

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