Struct PositionMessage 

pub struct PositionMessage {
    pub position: [f32; 3],
    pub quaternion: [f32; 4],
}

POSITION message containing position and quaternion orientation

OpenIGTLink Specification

• Message type: “POSITION” (alias: “QTRANS”)
• Body size: 28 bytes (7 × 4-byte floats)
• Encoding: Big-endian
• Position in millimeters, orientation as quaternion

Fields

position: [f32; 3]

Position in millimeters

quaternion: [f32; 4]

Orientation as quaternion

Quaternion components in order: [ox, oy, oz, w] where q = w + oxi + oyj + oz*k

Implementations

impl PositionMessage

pub fn identity() -> Self

Create a new POSITION message at origin with identity orientation

pub fn new(x: f32, y: f32, z: f32) -> Self

Create a new POSITION message with specified position and identity orientation

pub fn with_quaternion(position: [f32; 3], quaternion: [f32; 4]) -> Self

Create a new POSITION message with position and quaternion

pub fn get_position(&self) -> (f32, f32, f32)

Get position coordinates

pub fn get_quaternion(&self) -> (f32, f32, f32, f32)

Get quaternion components

Trait Implementations

impl Clone for PositionMessage

fn clone(&self) -> PositionMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PositionMessage

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

Formats the value using the given formatter.

impl Message for PositionMessage

fn message_type() -> &'static str

Returns the message type name (e.g., “TRANSFORM”, “IMAGE”)

fn encode_content(&self) -> Result<Vec<u8>>

Encode message content to bytes

fn decode_content(data: &[u8]) -> Result<Self>

Decode message content from bytes

impl PartialEq for PositionMessage

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