Enum ruma_common::events::call::SessionDescriptionType

#[non_exhaustive]
pub enum SessionDescriptionType {
    Answer,
    Offer,
    PrAnswer,
    Rollback,
    // some variants omitted
}

Available on crate feature events only.

The type of VoIP session description.

This is the same type as WebRTC’s RTCSdpType.

This type can hold an arbitrary string. To build this with a custom value, convert it from a string with ::from() / .into(). To check for values that are not available as a documented variant here, use its string representation, obtained through .as_str().

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Answer

The description must be treated as an SDP final answer, and the offer-answer exchange must be considered complete.

Offer

The description must be treated as an SDP offer.

PrAnswer

Available on crate feature unstable-msc2746 only.

The description must be treated as an SDP answer, but not final.

Rollback

Available on crate feature unstable-msc2746 only.

The description must be treated as cancelling the current SDP negotiation and moving the SDP offer back to what it was in the previous stable state.

Implementations

impl SessionDescriptionType

pub fn as_str(&self) -> &str

Creates a string slice from this SessionDescriptionType.

Trait Implementations

impl AsRef<str> for SessionDescriptionType

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for SessionDescriptionType

fn clone(&self) -> SessionDescriptionType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SessionDescriptionType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SessionDescriptionType

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where
    D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SessionDescriptionType

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

Formats the value using the given formatter.

impl<T> From<T> for SessionDescriptionTypewhere
    T: AsRef<str> + Into<Box<str>>,

fn from(s: T) -> Self

Converts to this type from the input type.

impl PartialEq<SessionDescriptionType> for SessionDescriptionType

fn eq(&self, other: &SessionDescriptionType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SessionDescriptionType

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where
    S: Serializer,

Serialize this value into the given Serde serializer.
