Struct stun_types::message::MessageHeader

pub struct MessageHeader { /* private fields */ }

The fixed length header of a STUN message. Allows reading the message header for a quick check if this message is a valid STUN message. Can also be used to expose the length of the complete message without needing to receive the entire message.

Implementations

impl MessageHeader

pub const LENGTH: usize = 20usize

The length of the STUN message header.

pub fn from_bytes(data: &[u8]) -> Result<Self, StunParseError>

Deserialize a MessageHeader

Examples

let msg_data = [0, 1, 0, 8, 33, 18, 164, 66, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 3, 232];
let message = MessageHeader::from_bytes(&msg_data).unwrap();
assert_eq!(message.get_type(), MessageType::from_class_method(MessageClass::Request, BINDING));
assert_eq!(message.transaction_id(), 1000.into());
assert_eq!(message.data_length(), 8);

pub fn data_length(&self) -> u16

The number of bytes of content in this MessageHeader. Adding both data_length() and MessageHeader::LENGTH will result in the size of the complete STUN message.

pub fn transaction_id(&self) -> TransactionId

The TransactionId of this MessageHeader

pub fn get_type(&self) -> MessageType

The MessageType of this MessageHeader
