Struct BlobObject 

#[non_exhaustive]
pub struct BlobObject {
    pub id: Id,
    pub content_type: Option<String>,
    pub size: Option<u64>,
    pub extra: Map<String, Value>,
}

A blob object returned in a Blob/convert (or Blob/set) response.

Spec: draft-ietf-jmap-blobext-01 §4 (BlobObject properties)

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 of the created blob.

content_type: Option<String>

MIME type of the blob, or None if the server did not report it.

size: Option<u64>

Size in octets. None if the server deferred generation and does not yet know the final size (spec §8 allows omitting size for deferred conversions).

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.
