Struct MetadataQAText 

pub struct MetadataQAText { /* private fields */ }

MetadataQAText is responsible for generating questions and answers from a given text chunk. It uses a templated prompt to interact with a client that implements the SimplePrompt trait.

Implementations

impl MetadataQAText

pub fn builder() -> MetadataQATextBuilder

Creates a new builder for the transformer

pub fn from_client(client: impl SimplePrompt + 'static) -> MetadataQATextBuilder

Build a new transformer from a client

pub fn new(client: impl SimplePrompt + 'static) -> Self

Create a new transformer from a client

pub fn with_concurrency(self, concurrency: usize) -> Self

Set the concurrency level for the transformer

impl Transformer for MetadataQAText

fn transform_node<'life0, 'async_trait>( &'life0 self, node: TextNode, ) -> Pin<Box<dyn Future<Output = Result<TextNode>> + Send + 'async_trait>>

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

Transforms an TextNode by generating questions and answers based on the text chunk within the node.

Arguments
