Message

Enum Message 

Source
pub enum Message {
    System {
        content: String,
    },
    User {
        content: OneOrMany<UserContent>,
    },
    Assistant {
        id: Option<String>,
        content: OneOrMany<AssistantContent>,
    },
}
Expand description

A message represents a run of input (user) and output (assistant). Each message type (based on it’s role) can contain a atleast one bit of content such as text, images, audio, documents, or tool related information. While each message type can contain multiple content, most often, you’ll only see one content type per message (an image w/ a description, etc).

Each provider is responsible with converting the generic message into it’s provider specific type using From or TryFrom traits. Since not every provider supports every feature, the conversion can be lossy (providing an image might be discarded for a non-image supporting provider) though the message being converted back and forth should always be the same.
