Struct RoomTopicEventContent 

#[non_exhaustive]
pub struct RoomTopicEventContent {
    pub topic: String,
    pub topic_block: TopicContentBlock,
}

The content of an m.room.topic event.

A topic is a short message detailing what is currently being discussed in the room.

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.

topic: String

The topic as plain text.

This SHOULD duplicate the content of the text/plain representation in topic_block if any exists.

topic_block: TopicContentBlock

Textual representation of the room topic in different mimetypes.

With the compat-lax-room-topic-deser cargo feature, this field is ignored if its deserialization fails.

Implementations
