Trait FilterFn 

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

Filter function.

Required Methods

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

Executes the filter function.

Errors

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