Struct GridTransform 

#[non_exhaustive]
pub struct GridTransform {
    pub source_kind: LatticeKind,
    pub matrix: [[i32; 2]; 2],
    pub offset: [i32; 2],
}

A lattice-coordinate symmetry transform: out = matrix * coord + offset.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

source_kind: LatticeKind

Lattice family this transform belongs to.

matrix: [[i32; 2]; 2]

Row-major 2x2 integer linear part.

offset: [i32; 2]

Integer offset applied after the linear part.

Implementations

impl GridTransform

pub const fn new( source_kind: LatticeKind, matrix: [[i32; 2]; 2], offset: [i32; 2], ) -> Self

Construct a lattice transform from raw components.

pub fn apply(self, coord: Coord) -> Coord

Apply this transform to a coordinate.

pub const fn determinant(self) -> i32

Determinant of the linear part.

Trait Implementations

impl Clone for GridTransform

fn clone(&self) -> GridTransform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GridTransform

impl Debug for GridTransform

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

Formats the value using the given formatter.

impl Eq for GridTransform

impl Hash for GridTransform

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 GridTransform

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