Struct SimpleTransform

pub struct SimpleTransform<T> {
    pub mirror: bool,
    pub rotation: Angle,
    pub magnification: T,
    pub displacement: Vector<T>,
}

Describes a geometric transformation that consists of a optional mirroring along the x-axis followed by a rotation by a multiple of 90 degrees followed by a displacement.

Fields

mirror: bool

Mirror on the x-axis?

rotation: Angle

Rotation by a multiple of 90 degrees.

magnification: T

Enlargement.

displacement: Vector<T>

Translation.

Trait Implementations

impl<T: Clone> Clone for SimpleTransform<T>

fn clone(&self) -> SimpleTransform<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for SimpleTransform<T>

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

Formats the value using the given formatter.

impl<T: CoordinateType> Default for SimpleTransform<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: PartialEq> PartialEq for SimpleTransform<T>

fn eq(&self, other: &SimpleTransform<T>) -> 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.

type Output = SimpleTransform<Dst>

Output type of the cast. This is likely the same geometrical type just with other coordinate types.
