Struct GlobalTransform 

pub struct GlobalTransform(pub Mat4);

全局变换组件，表示世界空间中的最终变换。

GlobalTransform 通常由层次变换系统计算，表示对象在世界空间中的最终位置、旋转和缩放。 它使用 4x4 矩阵存储，以提供高效的变换操作。

Trait Implementations

impl Clone for GlobalTransform

fn clone(&self) -> GlobalTransform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GlobalTransform

impl Debug for GlobalTransform

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

Formats the value using the given formatter.

impl Default for GlobalTransform

fn default() -> Self

Returns the “default value” for a type.

impl From<Mat4> for GlobalTransform

fn from(matrix: Mat4) -> Self

Converts to this type from the input type.

impl From<Transform> for GlobalTransform

fn from(transform: Transform) -> Self

Converts to this type from the input type.

impl PartialEq for GlobalTransform

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