Struct Sample 

#[repr(C)]
pub struct Sample {
    pub rg: u16,
    pub b: u16,
    pub x: u16,
    pub y: u16,
}

A laser sample with position and color.

The LaserDock uses 12-bit coordinates (0-4095) where:

• X: 0 = left edge, 2047 = center, 4095 = right edge
• Y: 0 = bottom edge, 2047 = center, 4095 = top edge

Colors are 8-bit values (0-255).

Fields

rg: u16

Red (low byte) and Green (high byte) combined.

b: u16

Blue (low byte), high byte unused.

x: u16

X coordinate (12-bit, 0-4095).

y: u16

Y coordinate (12-bit, 0-4095).

Implementations

impl Sample

pub fn new(x: u16, y: u16, r: u8, g: u8, b: u8) -> Self

Create a new sample from individual components.

Arguments

• x - X coordinate (0-4095)
• y - Y coordinate (0-4095)
• r - Red intensity (0-255)
• g - Green intensity (0-255)
• b - Blue intensity (0-255)

pub fn blank() -> Self

Create a blank sample (laser off) at the center position.

pub fn red(&self) -> u8

Get the red component.

pub fn green(&self) -> u8

Get the green component.

pub fn blue(&self) -> u8

Get the blue component.

pub fn flip_x(&mut self)

Flip the X coordinate.

pub fn flip_y(&mut self)

Flip the Y coordinate.

pub fn to_bytes(&self) -> [u8; 8]

Convert the sample to raw bytes for USB transmission.

Trait Implementations

impl Clone for Sample

fn clone(&self) -> Sample

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sample

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

Formats the value using the given formatter.

impl Default for Sample

fn default() -> Sample

Returns the “default value” for a type.

impl From<&LaserPoint> for Sample

fn from(p: &LaserPoint) -> Self

Convert a LaserPoint to a LaserCube USB Sample.

LaserPoint uses f32 coordinates (-1.0 to 1.0) and u16 colors (0-65535). LaserCube USB uses 12-bit unsigned coordinates (0-4095) and u8 colors.

impl PartialEq for Sample

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