Struct BlobLookupEntry 

#[non_exhaustive]
pub struct BlobLookupEntry {
    pub id: Id,
    pub matched_ids: HashMap<String, Vec<Id>>,
    pub extra: Map<String, Value>,
}

A single entry in a Blob/lookup response.

Spec: draft-ietf-jmap-blobext-01 §6

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.

id: Id

The blobId that was queried.

matched_ids: HashMap<String, Vec<Id>>

Per-type reverse lookup: keys are JMAP data type names (e.g. "Message", "Chat"); values are the typed Ids of objects that reference this blob. The keys stay String because data type names are externally-defined spec strings and not uniformly enumerable across extensions.

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).

Constraint: keys in extra MUST NOT collide with the typed-field wire names above (the camelCase spelling — e.g. "accountId", "ids", "properties", "blobIds", "fromAccountId", etc.). On collision the typed-field value wins on the wire and the extra value is silently dropped at serialization. Place vendor extensions under vendor-prefixed keys (e.g. "acmeCorpFoo") to avoid the collision class.
