Enum Setup 

pub enum Setup {
    Active,
    Passive,
    ActPass,
    HoldConn,
}

Who opens the DTLS connection (RFC 4145 §4, used by RFC 5763 §5).

Variants

Active

This endpoint will start the handshake — the DTLS client.

Passive

This endpoint will wait for it — the DTLS server.

ActPass

Either; the answerer chooses. RFC 5763 §5 requires an offerer to use this.

HoldConn

No connection is to be formed, for an offer that is only describing a stream.

Implementations

impl Setup

pub fn as_str(self) -> &'static str

The token as it appears in SDP.

pub fn parse(token: &str) -> Option<Self>

The role a token names.

pub fn answer(offered: Self) -> Self

The role to answer an offered one with (RFC 4145 §4.1).

actpass is answered active, which is RFC 5763 §5’s recommendation and not merely a preference: the answerer starting the handshake means the offerer does not have to send packets to an address it has only just learned, which is what gets a DTLS ClientHello through a NAT the answerer sits behind.

holdconn is answered holdconn: §4.1 gives no other legal answer, and answering with a role would be agreeing to a connection the offerer said not to form.

pub fn is_client(self) -> bool

Whether holding this role makes this endpoint the DTLS client (RFC 8122 §6.2).

Trait Implementations

impl Clone for Setup

fn clone(&self) -> Setup

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Setup

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

Formats the value using the given formatter.

impl PartialEq for Setup

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

impl Copy for Setup

impl Eq for Setup

impl StructuralPartialEq for Setup
