Enum PromptMessageType 

pub enum PromptMessageType {
    System,
    User,
    Assistant,
    Function,
}

Represents the type of message in a prompt sequence.

Message types follow standard LLM conventions, supporting system-level instructions, user inputs, and assistant responses. The ordering and placement of these types is validated during prompt construction.

Variants

System

A system-level instruction that guides model behavior. Must be the first message if present.

User

A user input message. Cannot follow another user message directly.

Assistant

A response from the assistant. Cannot be the first message or follow another assistant message.

Function

A function calling message.

Implementations

pub fn as_str(&self) -> &str

Trait Implementations

impl Clone for PromptMessageType

fn clone(&self) -> PromptMessageType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PromptMessageType

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PromptMessageType

fn deserialize<__D>( __deserializer: __D, ) -> Result<PromptMessageType, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PromptMessageType

fn eq(&self, other: &PromptMessageType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PromptMessageType

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
