Struct MetadataKeywords

pub struct MetadataKeywords { /* private fields */ }

MetadataKeywords is responsible for generating keywords for a given text chunk. It uses a templated prompt to interact with a client that implements the SimplePrompt trait.

Implementations

impl MetadataKeywords

pub fn builder() -> MetadataKeywordsBuilder

Creates a new builder for the transformer

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

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

Trait Implementations

impl Clone for MetadataKeywords

fn clone(&self) -> MetadataKeywords

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MetadataKeywords

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Transformer for MetadataKeywords

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

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

Transforms an Node by extracting a keywords based on the text chunk within the node.

Arguments
