Struct StringMessage 

pub struct StringMessage {
    pub encoding: u16,
    pub string: String,
}

STRING message containing a text string with encoding information

OpenIGTLink Specification

• Message type: “STRING”
• Body format: ENCODING (uint16) + LENGTH (uint16) + STRING (uint8[LENGTH])
• Encoding: MIBenum value (default: 3 = US-ASCII)
• Max length: 65535 bytes

Fields

encoding: u16

Character encoding as MIBenum value

Common values:

• 3: US-ASCII (ANSI-X3.4-1968) - recommended

• 106: UTF-8

  See: http://www.iana.org/assignments/character-sets

string: String

The text content

Implementations

impl StringMessage

pub fn new(string: impl Into<String>) -> Self

Create a new STRING message with US-ASCII encoding (default)

pub fn utf8(string: impl Into<String>) -> Self

Create a STRING message with UTF-8 encoding

pub fn with_encoding(encoding: u16, string: impl Into<String>) -> Self

Create a STRING message with custom encoding

pub fn as_str(&self) -> &str

Get the string content as a reference

pub fn len(&self) -> usize

Get the length of the string in bytes

pub fn is_empty(&self) -> bool

Check if the string is empty

Trait Implementations

impl Clone for StringMessage

fn clone(&self) -> StringMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StringMessage

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

Formats the value using the given formatter.

impl From<&str> for StringMessage

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for StringMessage

fn from(s: String) -> Self

Converts to this type from the input type.

impl Message for StringMessage

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 StringMessage

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