Struct FewShotChatMessagePromptTemplate 

pub struct FewShotChatMessagePromptTemplate { /* private fields */ }

A few-shot chat message prompt template that injects examples before the user query.

Each example is formatted as a Human message (input) followed by an AI message (output). An optional prefix system message can be provided.

Implementations

impl FewShotChatMessagePromptTemplate

pub fn new(examples: Vec<FewShotExample>, suffix: PromptTemplate) -> Self

pub fn with_prefix(self, prefix: PromptTemplate) -> Self

pub fn format( &self, values: &HashMap<String, String>, ) -> Result<Vec<Message>, SynapticError>

Trait Implementations

impl Runnable<HashMap<String, String>, Vec<Message>> for FewShotChatMessagePromptTemplate

fn invoke<'life0, 'life1, 'async_trait>( &'life0 self, input: HashMap<String, String>, _config: &'life1 RunnableConfig, ) -> Pin<Box<dyn Future<Output = Result<Vec<Message>, SynapticError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Execute this runnable on a single input.

fn batch<'life0, 'life1, 'async_trait>( &'life0 self, inputs: Vec<I>, config: &'life1 RunnableConfig, ) -> Pin<Box<dyn Future<Output = Vec<Result<O, SynapticError>>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Execute this runnable on multiple inputs sequentially.

fn stream<'a>( &'a self, input: I, config: &'a RunnableConfig, ) -> Pin<Box<dyn Stream<Item = Result<O, SynapticError>> + Send + 'a>>

where I: 'a,

Stream the output. Default wraps invoke as a single-item stream. Override for true streaming (e.g., token-by-token from an LLM).

fn boxed(self) -> BoxRunnable<I, O>

where Self: Sized + 'static,

Wrap this runnable into a type-erased BoxRunnable for composition via |.
