Struct Trans 

pub struct Trans {
    pub rot: Rot4,
    pub mirror: bool,
    pub disp: Vec2,
}

Exact orthogonal transform: optional mirror about X axis, then rotation, then translation. Composition is exact; coordinates stay on grid.

Fields

rot: Rot4

mirror: bool

disp: Vec2

Implementations

impl Trans

pub const IDENTITY: Self

pub const fn new(rot: Rot4, mirror: bool, disp: Vec2) -> Self

pub fn translate(disp: Vec2) -> Self

pub fn rotate(rot: Rot4) -> Self

pub fn mirror_x() -> Self

pub fn apply(self, p: Point) -> Point

pub fn apply_bbox(self, b: Bbox) -> Bbox

pub fn compose(self, other: Trans) -> Trans

Composition: (self * other).apply(p) == self.apply(other.apply(p)).

pub fn inverse(self) -> Trans

Trait Implementations

impl Clone for Trans

fn clone(&self) -> Trans

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Trans

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

Formats the value using the given formatter.

impl Default for Trans

fn default() -> Self

Returns the “default value” for a type.

impl Hash for Trans

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 PartialEq for Trans

fn eq(&self, other: &Trans) -> 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 Copy for Trans
