Struct langchain_rust::chain::StuffDocument

pub struct StuffDocument { /* private fields */ }

Implementations

impl StuffDocument

pub fn new(llm_chain: LLMChain) -> Self

pub fn qa_prompt_builder<'a>(&self) -> StuffQAPromptBuilder<'a>

pub fn load_stuff_qa<L: LLM + 'static>(llm: L) -> Self

load_stuff_qa return an instance of StuffDocument with a prompt desiged for question ansering

Example

let llm = OpenAI::default();
let chain = StuffDocument::load_stuff_qa(llm);

let input = chain
.qa_prompt_builder()
.documents(&[
Document::new(format!(
"\nQuestion: {}\nAnswer: {}\n",
"Which is the favorite text editor of luis", "Nvim"
)),
Document::new(format!(
"\nQuestion: {}\nAnswer: {}\n",
"How old is Luis", "24"
)),
])
.question("How old is luis and whats his favorite text editor")
.build();

let ouput = chain.invoke(input).await.unwrap();

println!("{}", ouput);

pub fn load_stuff_qa_with_options<L: LLM + 'static>( llm: L, opt: ChainCallOptions ) -> Self

load_stuff_qa_with_options return an instance of StuffDocument with a prompt desiged for question ansering

Example

let llm = OpenAI::default();
let chain = StuffDocument::load_stuff_qa_with_options(llm,ChainCallOptions::default());

let input = chain
.qa_prompt_builder()
.documents(&[
Document::new(format!(
"\nQuestion: {}\nAnswer: {}\n",
"Which is the favorite text editor of luis", "Nvim"
)),
Document::new(format!(
"\nQuestion: {}\nAnswer: {}\n",
"How old is Luis", "24"
)),
])
.question("How old is luis and whats his favorite text editor")
.build();

let ouput = chain.invoke(input).await.unwrap();

println!("{}", ouput);

Trait Implementations

impl Chain for StuffDocument

fn call<'life0, 'async_trait>( &'life0 self, input_variables: PromptArgs ) -> Pin<Box<dyn Future<Output = Result<GenerateResult, ChainError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Call the Chain and receive as output the result of the generation process along with additional information like token consumption. The input is a set of variables passed as a PromptArgs hashmap.

fn stream<'life0, 'async_trait>( &'life0 self, input_variables: PromptArgs ) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = Result<StreamData, ChainError>> + Send>>, ChainError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Stream the Chain and get an asynchronous stream of chain generations. The input is a set of variables passed as a PromptArgs hashmap. If the chain have memroy, the tream method will not be able to automaticaly set the memroy, bocause it will not know if the how to extract the output message out of the stram

fn get_input_keys(&self) -> Vec<String>

fn invoke<'life0, 'async_trait>( &'life0 self, input_variables: PromptArgs ) -> Pin<Box<dyn Future<Output = Result<String, ChainError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Invoke the Chain and receive just the generation result as a String. The input is a set of variables passed as a PromptArgs hashmap.

fn execute<'life0, 'async_trait>( &'life0 self, input_variables: PromptArgs ) -> Pin<Box<dyn Future<Output = Result<HashMap<String, Value>, ChainError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Execute the Chain and return the result of the generation process along with additional information like token consumption formatted as a HashMap. The input is a set of variables passed as a PromptArgs hashmap. The key for the generated output is specified by the get_output_keys method (default key is output).
