Struct CallNegotiateEventContent 

#[non_exhaustive]
pub struct CallNegotiateEventContent {
    pub call_id: OwnedVoipId,
    pub party_id: OwnedVoipId,
    pub version: VoipVersionId,
    pub lifetime: UInt,
    pub description: SessionDescription,
    pub sdp_stream_metadata: BTreeMap<String, StreamMetadata>,
}

Available on crate feature events only.

Added in VoIP version 1. The content of an m.call.negotiate event.

This event is sent by either party after the call is established to renegotiate it. It can be used for media pause, hold/resume, ICE restarts and voice/video call up/downgrading.

First an event must be sent with an offer session description, which is replied to with an event with an answer session description.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

call_id: OwnedVoipId

The ID of the call this event relates to.

party_id: OwnedVoipId

The unique ID for this session for the duration of the call.

Must be the same as the one sent by the previous invite or answer from this session.

version: VoipVersionId

The version of the VoIP specification this messages adheres to.

lifetime: UInt

The time in milliseconds that the negotiation is valid for.

description: SessionDescription

The session description of the negotiation.

sdp_stream_metadata: BTreeMap<String, StreamMetadata>

Metadata describing the streams that will be sent.

This is a map of stream ID to metadata about the stream.
