Trait DynFunction 

pub trait DynFunction<A, T>
where
    T: TypeSet,
{
    // Required method
    fn call(
        &self,
        ctx: &mut T,
        args: &[TypedValue<T>],
    ) -> Result<TypedValue<T>, FunctionCallError>;
}

Functions and closures that implement this trait can be registered as functions to be called by expressions.

Required Methods

fn call( &self, ctx: &mut T, args: &[TypedValue<T>], ) -> Result<TypedValue<T>, FunctionCallError>

Call the function with the specified arguments.

Errors

This functions returns an error if:

• The number of arguments is incorrect
• The types of arguments are incorrect
