Trait FilterMapFn 

pub trait FilterMapFn<A, I, T, U>: Send + 'static {
    // Required method
    fn execute(&self, scope: &mut Scope<I>, value: T) -> Result<Option<U>>;
}

Filter map function.

Required Methods

fn execute(&self, scope: &mut Scope<I>, value: T) -> Result<Option<U>>

Executes the filter map function.

Errors

This method returns an error if the function fails to execute.

Dyn Compatibility

This trait is dyn compatible.

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