Trait MutatingExpression 

pub trait MutatingExpression: Send + Sync {
    // Required method
    fn evaluate<'life0, 'life1, 'async_trait>(
        &'life0 self,
        exchange: &'life1 mut Exchange,
    ) -> Pin<Box<dyn Future<Output = Result<Value, LanguageError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

Expression that may modify the Exchange during evaluation. Changes to headers, properties, or body are propagated back.

Required Methods

fn evaluate<'life0, 'life1, 'async_trait>( &'life0 self, exchange: &'life1 mut Exchange, ) -> Pin<Box<dyn Future<Output = Result<Value, LanguageError>> + Send + 'async_trait>>

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

Dyn Compatibility

This trait is dyn compatible.

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