Struct Relation 

#[non_exhaustive]
pub struct Relation {
    pub at_type: String,
    pub relation: Option<BTreeMap<String, bool>>,
    pub extra: Map<String, Value>,
}

A relationship between this object and another, identified by UID (RFC 8984 §1.4.10).

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.

at_type: String

Object type discriminator; always "Relation" on the wire.

Deserialize is liberal: if @type is absent (spec-violating vendor input), this field defaults to "Relation" rather than failing the whole parent object’s deserialize. Serialize always emits the field. See bd:JMAP-ky8g.10.

relation: Option<BTreeMap<String, bool>>

Map of relationship type URIs → true.

extra: Map<String, Value>

Catch-all for vendor / site / private extension fields not covered by the typed fields above. Preserves unknown fields across deserialize/serialize round-trip per workspace extras-preservation policy (see workspace AGENTS.md).
