Enum Relation 

#[non_exhaustive]
pub enum Relation {
    Reply {
        in_reply_to: InReplyTo,
    },
    Replacement(Replacement),
    Reference(Reference),
    Annotation(Annotation),
    Thread(Thread),
}
Expand description

Relationship information about an encrypted event.

Outside of the encrypted payload to support server aggregation.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

Reply

An m.in_reply_to relation indicating that the event is a reply to another event.

Fields

§in_reply_to: InReplyTo

Information about another message being replied to.

§

Replacement(Replacement)

An event that replaces another event.

§

Reference(Reference)

A reference to another event.

§

Annotation(Annotation)

An annotation to an event.

§

Thread(Thread)

An event that belongs to a thread.

Implementations§

§

impl Relation

pub fn rel_type(&self) -> Option<RelationType>

The type of this Relation.

Returns an Option because the Reply relation does not have arel_type field.

pub fn data(&self) -> Cow<'_, Map<String, Value>>

The associated data.

The returned JSON object holds the contents of m.relates_to, including rel_type and event_id if present, but not things like m.new_content for m.replace relations that live next to m.relates_to.

Prefer to use the public variants of Relation where possible; this method is meant to be used for custom relations only.
