Crate jmap_metadata_types 

JMAP Object Metadata extension data types.

Implements the data types defined in draft-ietf-jmap-metadata-01. Types only — no method handlers, no async, no network I/O.

Module layout

• metadata — Metadata, Annotation, ImapMetadata, WebDavMetadata (§2)
• capability — MetadataCapability, JMAP_METADATA_URI (§1.2.1)
• filter — MetadataFilterCondition (§3.4.1)
• backend — MetadataProperty and JmapObject trait impls

All public types are re-exported at the crate root.

Example

use jmap_metadata_types::{Annotation, Metadata};

let json = r#"{
    "@type": "Annotation",
    "id": "MD789",
    "relatedType": "Email",
    "relatedId": "EM456",
    "isPrivate": true,
    "acme.example.com:workflowState": "pending-review"
}"#;

let meta: Metadata = serde_json::from_str(json).unwrap();
match meta {
    Metadata::Annotation(Annotation { ref related_type, ref extra, .. }) => {
        assert_eq!(related_type, "Email");
        assert_eq!(
            extra.get("acme.example.com:workflowState"),
            Some(&serde_json::Value::String("pending-review".into())),
        );
    }
    _ => panic!("expected Annotation variant"),
}
