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.
