Trait ConditionalEdge 

pub trait ConditionalEdge<S: StateSchema>: Send + Sync {
    // Required method
    fn route<'life0, 'life1, 'async_trait>(
        &'life0 self,
        state: &'life1 S,
    ) -> Pin<Box<dyn Future<Output = Result<String, GraphError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

Conditional routing function trait

Routing functions examine the state and return a string key that maps to the next node via the edge’s target map.

Required Methods

fn route<'life0, 'life1, 'async_trait>( &'life0 self, state: &'life1 S, ) -> Pin<Box<dyn Future<Output = Result<String, GraphError>> + Send + 'async_trait>>

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

Route to next node based on state

Returns a string key that matches entries in the edge’s targets map.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
