Struct SendMessageOptions 

pub struct SendMessageOptions {
    pub priority: Option<MessagePriority>,
    pub reply_to_msg: Option<String>,
    pub content_type: Option<ContentType>,
    pub reply_context: Option<ReplyContext>,
    pub media_metadata: Option<MediaMetadata>,
    pub forward_info: Option<ForwardInfo>,
    pub via_transport: Option<TransportType>,
}

Options for OfflineProtocol::send_message_with: priority and reply threading (as on send_message), plus the rich fields introduced with the sealed rich payload.

The rich fields (reply_context, media_metadata, forward_info) only ever travel inside the MLS-sealed __RICH_V1__ body, and only toward recipients whose key package advertised rich_versions support. Toward anyone else they are silently dropped — never sent cleartext — so the message degrades to plain text with reply_to_msg threading intact.

Fields

priority: Option<MessagePriority>

Message priority (defaults to Medium).

reply_to_msg: Option<String>

ID of the message this is replying to.

content_type: Option<ContentType>

Content type stamped on the outer message (defaults to Text). A coarse rendering hint — the actual content stays MLS-sealed. Toward a recipient that advertised the sealed rich payload, a copy travels inside the sealed body — whenever extras seal, or the hint itself is non-Text — and the receiver treats that copy as authoritative, so a relay cannot rewrite the hint. Must not be ContentType::FileChunk (an internal transport content type; the receiver would route the message into its file-transfer manager and drop it) — rejected as InvalidArgument.

reply_context: Option<ReplyContext>

Quoted-reply context, delivered sealed-only.

media_metadata: Option<MediaMetadata>

Rich media metadata (cloud attachments, stickers — including any encryption_key/iv secrets), delivered sealed-only.

forward_info: Option<ForwardInfo>

Forward attribution, delivered sealed-only.

via_transport: Option<TransportType>

Send via this specific transport (bypassing DORS selection), like send_message_via_transport.
