Struct MessageFactory 

pub struct MessageFactory;

Message factory for creating messages dynamically based on type name

This factory allows receiving and decoding messages without knowing the type at compile time. The message type is determined from the header’s type_name field.

Examples

let factory = MessageFactory::new();
let message = factory.decode_any(&header, body, true)?;
println!("Received {} message", message.message_type());

Implementations

impl MessageFactory

pub fn new() -> Self

Create a new message factory

pub fn decode_any( &self, header: &Header, body: &[u8], verify_crc: bool, ) -> Result<AnyMessage>

Decode a message from header and body bytes

Arguments

• header - Parsed message header
• body - Raw body bytes (may include extended header, content, and metadata)
• verify_crc - Whether to verify CRC checksum

Returns

AnyMessage containing the decoded message, or AnyMessage::Unknown if the message type is not recognized.

Examples

let factory = MessageFactory::new();
let message = factory.decode_any(&header, body, true)?;

match message {
    openigtlink_rust::protocol::AnyMessage::Transform(msg) => {
        println!("Transform from {}", msg.header.device_name.as_str()?);
    }
    openigtlink_rust::protocol::AnyMessage::Unknown { .. } => {
        println!("Unknown message type");
    }
    _ => {}
}

Trait Implementations

impl Default for MessageFactory

fn default() -> Self

Returns the “default value” for a type.
