Enum Direction 

pub enum Direction {
    SendRecv,
    SendOnly,
    RecvOnly,
    Inactive,
}

Which way media flows, from the point of view of the description that carries it.

Variants

SendRecv

Both ways. The default when no direction attribute is present (RFC 4566 §6).

SendOnly

This side sends only.

RecvOnly

This side receives only.

Inactive

Neither, but the stream stays negotiated.

Implementations

impl Direction

pub fn mirrored(self) -> Self

The direction an answer must carry to match an offer.

This is a mirror, not a copy. An offer of sendonly means “I will send, you will receive”, so the answer says recvonly. Copying the offer’s direction instead is a common bug and produces a call where both ends wait for audio.

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

Parse a direction attribute name.

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

The attribute name.

pub fn sends(self) -> bool

Whether this side will send media.

pub fn receives(self) -> bool

Whether this side will receive media.

Trait Implementations

impl Clone for Direction

fn clone(&self) -> Direction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Direction

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

Formats the value using the given formatter.

impl Default for Direction

fn default() -> Direction

Returns the “default value” for a type.

impl PartialEq for Direction

fn eq(&self, other: &Direction) -> 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 Direction
