Struct MediaSendOptions 

pub struct MediaSendOptions {
    pub media_metadata: Option<MediaMetadata>,
    pub caption: Option<String>,
    pub reply_to_msg: Option<String>,
    pub reply_context: Option<ReplyContext>,
    pub forward_info: Option<ForwardInfo>,
    pub file_id: Option<String>,
}

Options for OfflineProtocol::send_media_with: the chunk-0 media metadata (as on send_media), plus the rich fields introduced with the sealed rich payload and an optional caller-supplied file_id.

The rich fields (caption, reply_to_msg, reply_context, forward_info) only ever travel inside the MLS-sealed chunk-0 plaintext (v2 media envelope), and only toward recipients whose key package advertised rich_versions support. Toward anyone else — including every plaintext (encryption opt-out) transfer — they are silently dropped, never sent cleartext, so the transfer degrades to what plain send_media sends.

Fields

media_metadata: Option<MediaMetadata>

Media metadata delivered with chunk 0 (as on send_media).

caption: Option<String>

Caption text, delivered sealed-only.

reply_to_msg: Option<String>

ID of the message this media replies to, delivered sealed-only.

reply_context: Option<ReplyContext>

Quoted-reply context, delivered sealed-only.

forward_info: Option<ForwardInfo>

Forward attribution, delivered sealed-only.

file_id: Option<String>

Caller-supplied file id for the transfer (minted when absent). Must not collide with an active outbound transfer; bounded to the wire file_id field limit.
