Struct MessagePart 

pub struct MessagePart {
    pub id: Uuid,
    pub message_id: Uuid,
    pub part_type: MessagePartType,
    pub content: Value,
    pub number: u32,
    pub file_citations: Vec<FileCitation>,
    pub link_citations: Vec<LinkCitation>,
    pub references: Vec<LinkReference>,
}

A persisted, ordered fragment of a message body.

A message owns one or more parts; the parts in number order are the message body. Persisted in the message_parts table with a CASCADE foreign key to messages (see DESIGN cpt-cf-chat-engine-design-entity-message-part).

Fields

id: Uuid

Unique part identifier (primary key).

message_id: Uuid

Message this part belongs to.

part_type: MessagePartType

Discriminates the content shape.

content: Value

Typed payload; shape determined by part_type.

number: u32

0-based ordinal within the message; unique per message.

file_citations: Vec<FileCitation>

Document citations attached to this part (only text parts carry these).

link_citations: Vec<LinkCitation>

Web-page citations attached to this part.

references: Vec<LinkReference>

Lightweight URL references attached to this part.
