Struct Chain

pub struct Chain { /* private fields */ }

Chain represents a conversation between an entity and an LLM.

It holds the conversation state and provides methods for sending messages and receiving responses.

Implementations

impl Chain

pub fn new(state: PromptTemplate) -> Result<Chain, StringTemplateError>

Constructs a new Chain with the given conversation state. Self,

Arguments

• state - The initial prompt state to use.

pub fn new_with_message_collection( state: &ChatMessageCollection<String>, ) -> Chain

Constructs a new Chain with the given conversation state by passing a ChatMessageCollection (clone). Self,

Arguments

• state - The initial prompt state to use.

pub async fn send_message<E: Executor>( &mut self, step: Step, parameters: &Parameters, exec: &E, ) -> Result<Output, Error>

Sends a message to the LLM and returns the response.

This method sends a message to the LLM, adding it and the response to the internal state.

Arguments

• step - The step to send.
• parameters - The parameters to use when formatting the step.
• exec - The executor to use.

Returns

A Result containing the LLM’s response as E::Output on success or an Error variant on failure.

pub async fn send_message_raw<E: Executor>( &mut self, options: &Options, prompt: &Prompt, exec: &E, ) -> Result<Output, Error>

Sends a message to the LLM and returns the response.

This method takes a ready prompt and options and sends it to the LLM, adding it and the response to the internal state.

Arguments

• options - The options to use when executing the prompt.
• prompt - The prompt to send.
• exec - The executor to use.

Returns

A Result containing the LLM’s response as E::Output on success or an Error variant on failure.
