Struct UserMessage 

pub struct UserMessage {
    pub role: UserRole,
    pub content: MessageContent,
    pub timestamp: i64,
    pub visible: bool,
}

Stable since 0.63.0

Message types for constructing conversations. User message sent to the model.

Fields

role: UserRole

Role discriminator (always UserRole::User).

content: MessageContent

Message content – either a plain string or a list of content blocks.

timestamp: i64

Unix-epoch milliseconds when the message was created.

visible: bool

Whether this message renders in the transcript. false for synthetic reminders/nudges the model must see but the human should not (they are not something the human typed). Always sent to the provider regardless of this flag — it is display-only metadata. Missing on old session files deserializes to true (backward compat).

pub fn new(content: impl Into<MessageContent>) -> Self

Create a new user message with the current timestamp.
