Enum rustun::message::Class

pub enum Class {
    Request,
    Indication,
    SuccessResponse,
    ErrorResponse,
}

The class of a message.

The class indicates whether this is a request, a success response, an error response, or an indication.

RFC 5389 -- 3. Overview of Operation

An instance of Class can be casted to the corresponding u8 value.

use rustun::message::Class;

assert_eq!(Class::Request as u8, 0b00);
assert_eq!(Class::Indication as u8, 0b01);
assert_eq!(Class::SuccessResponse as u8, 0b10);
assert_eq!(Class::ErrorResponse as u8, 0b11);

RequestIndicationSuccessResponseErrorResponse

Methods

impl Class

fn from_u8(value: u8) -> Option<Self>

Returns a Class instance which is corresponding to value.

A class of 0b00 is a request, a class of 0b01 is an indication, a class of 0b10 is a success response, and a class of 0b11 is an error response.

RFC 5389 -- 6. STUN Message Structure

If no such instance exists, this will return None.

Examples

use rustun::message::Class;

assert_eq!(Class::from_u8(0), Some(Class::Request));
assert_eq!(Class::from_u8(9), None);
