Types

type Array

type Array[T any] struct {
	// contains filtered or unexported fields
}

Array is a generic 2D array.

func New

func New[T any](w, h int) (a Array[T])

New creates empty array with given dimensions.

func (Array[T]) Bounds

func (a Array[T]) Bounds() (w, h int)

Bounds returns width and height of array.

func (*Array[T]) Fill

func (a *Array[T]) Fill(fn func() T)

Fill fills array with given function.

func (Array[T]) Get

func (a Array[T]) Get(x, y int) (rv T, ok bool)

Get returns value at given coords, if any.

func (*Array[T]) Iter

func (a *Array[T]) Iter(it func(x, y int, v T) bool)

Iter iterates over array items.

func (Array[T]) Len

func (a Array[T]) Len() (rv int)

Len returns length of array.

func (*Array[T]) Set

func (a *Array[T]) Set(x, y int, v T) (ok bool)

Set sets value at given coords.
