Struct QtDataMessage 

pub struct QtDataMessage {
    pub elements: Vec<TrackingElement>,
}

QTDATA message containing multiple tracking elements

OpenIGTLink Specification

• Message type: “QTDATA”
• Each element: NAME (char[20]) + TYPE (uint8) + Reserved (uint8) + POSITION (float32[3]) + QUATERNION (float32[4])
• Element size: 20 + 1 + 1 + 12 + 16 = 50 bytes

Fields

elements: Vec<TrackingElement>

List of tracking elements

Implementations

impl QtDataMessage

pub fn new(elements: Vec<TrackingElement>) -> Self

Create a new QTDATA message with elements

pub fn empty() -> Self

Create an empty QTDATA message

pub fn add_element(&mut self, element: TrackingElement)

Add a tracking element

pub fn len(&self) -> usize

Get number of tracking elements

pub fn is_empty(&self) -> bool

Check if message has no elements

Trait Implementations

impl Clone for QtDataMessage

fn clone(&self) -> QtDataMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QtDataMessage

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

Formats the value using the given formatter.

impl Message for QtDataMessage

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 QtDataMessage

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