Trait Implementations

impl Chain for LLMChain

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

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

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 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 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 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).
