Struct MetadataChangesParams 

pub struct MetadataChangesParams {
    pub filter_related_type: Option<String>,
    pub filter_metadata_type: Option<Vec<String>>,
    pub extra: Map<String, Value>,
}

Extra method-level arguments for Metadata/changes (draft-ietf-jmap-metadata-01 §3.3).

Both fields are optional. Pass None (or Default::default()) to fetch all Metadata changes regardless of relatedType or @type.

Per §3.3, when both filters are specified the server MUST return only changes to Metadata objects that satisfy both criteria (logical AND). The state token returned in the response represents the complete account state and is independent of the filters; clients that use these filters MUST re-use the same filter values across subsequent Metadata/changes calls to ensure consistent synchronisation.

Fields

filter_related_type: Option<String>

Restrict the created/updated/destroyed arrays in the response to Metadata objects whose relatedType equals this value (draft-ietf-jmap-metadata-01 §3.3).

filter_metadata_type: Option<Vec<String>>

Restrict the created/updated/destroyed arrays in the response to Metadata objects whose @type is in this list (draft-ietf-jmap-metadata-01 §3.3).

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).
