Enum Origin 

pub enum Origin {
    TopLeft,
    BottomLeft,
}

Coordinate system origin location

Determines where (0,0) is located on the display.

Examples

use unicorn_hat::Origin;

let origin = Origin::TopLeft;  // Default: (0,0) at top-left
let origin = Origin::BottomLeft;  // (0,0) at bottom-left (useful for bar graphs)

Variants

TopLeft

Origin at top-left, Y increases downward (default)

(0,0) ──────► (7,0)
  │
  ▼
(0,7)       (7,7)

BottomLeft

Origin at bottom-left, Y increases upward

Useful for bar graphs and charts where Y represents a value.

(0,7)       (7,7)
  ▲
  │
(0,0) ──────► (7,0)

Implementations

impl Origin

pub fn apply(&self, x: usize, y: usize) -> (usize, usize)

Transforms coordinates based on origin setting

Arguments

• x - X coordinate (0-7)
• y - Y coordinate (0-7)

Returns

Tuple of (transformed_x, transformed_y) in top-left coordinate space

Trait Implementations

impl Clone for Origin

fn clone(&self) -> Origin

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Origin

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

Formats the value using the given formatter.

impl Default for Origin

fn default() -> Origin

Returns the “default value” for a type.

impl PartialEq for Origin

fn eq(&self, other: &Origin) -> 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 Origin
