/// The `main!` macro is used to register a list of Azure Functions with
/// the Azure Functions host.
///
/// This macro expects a comma-separated list of functions that have the
/// #[func] attribute applied.
///
/// # Examples
///
/// ```rust,ignore
/// azure_functions::main!{
///     module::my_azure_function
/// }
/// ```
#[proc_macro]

    main::attr_impl(input)
}

/// Implements the `func` attribute.
///
/// This attribute is used to turn a Rust function into an Azure Function.
///
/// # Examples
///
/// ```rust,ignore
/// use azure_functions::func;
/// use azure_functions::bindings::HttpRequest;
///
/// #[func]
/// pub fn example(req: &HttpRequest) {
/// }
#[proc_macro_attribute]
