RoomTopicEventContent

matrix_sdk::ruma::events::room::topic

Struct RoomTopicEventContent

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

Expand description

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)§

This struct is marked as 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§

impl RoomTopicEventContent

pub fn new(topic: String) -> RoomTopicEventContent

Creates a new RoomTopicEventContent with the given plain text topic.

pub fn html( plain: impl Into<String>, html: impl Into<String>, ) -> RoomTopicEventContent

Convenience constructor to create a new HTML topic with a plain text fallback.

pub fn markdown(topic: impl AsRef<str> + Into<String>) -> RoomTopicEventContent

Convenience constructor to create a topic from Markdown.

The content includes an HTML topic if some Markdown formatting was detected, otherwise only a plain text topic is included.
