Struct FunctionNode 

pub struct FunctionNode { /* private fields */ }

Function node - wraps an async function as a node

Implementations

impl FunctionNode

pub fn new<F, Fut>(name: &str, func: F) -> Self

where F: Fn(NodeContext) -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<NodeOutput>> + Send + 'static,

Create a new function node

Trait Implementations

impl Node for FunctionNode

fn name(&self) -> &str

Node identifier

fn execute<'life0, 'life1, 'async_trait>( &'life0 self, ctx: &'life1 NodeContext, ) -> Pin<Box<dyn Future<Output = Result<NodeOutput>> + Send + 'async_trait>>

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

Execute the node and return state updates

fn execute_stream<'a>( &'a self, ctx: &'a NodeContext, ) -> Pin<Box<dyn Stream<Item = Result<StreamEvent>> + Send + 'a>>

Stream execution events (default: wraps execute)
