Crate function_group

The function_group macro is used to create a single function that accepts mutltiple types of arguments. Function groups can take multiple types of arguments and even be recursive, the general form of the function_group macro is displayed below.

Syntax

function_group! {
    fn name_of_function -> return_type_of_function {
        (argument_name_of_function : arugment_type_of_function...) {
            // body of function
        }
        (argument_name_of_function : ArgumentName...) {
            // body of function
        }
        ...
    }
}

Function groups can also be declared on types to do this there is an additonal parameter that comes after the function name and follows the form of ((&self | self | &mut self) : TypeTheFunctionWillBeImplementedOn). for example:

function_group! {
    fn name_of_function(self : AwsomeStruct) {
        (argument_name_of_function : ArgumentName ...) {
            // body of function
        }
        (argument_name_of_function : ArgumentName...) {
            // body of function
        }
        ...
    }
}
