/// A macro for easily implementing the `Attachable` trait for types with an
/// `attachments` field.
///
/// The `impl_attachable!` macro automatically generates an implementation of
/// the `Attachable` trait for any type that has an `attachments: Attachments`
/// field. This removes boilerplate code and ensures consistent implementations
/// across the codebase.
///
/// # Usage Requirements
/// The target type must have an `attachments: Attachments` field for this macro
/// to work. It will automatically implement the required `attachments()` and
/// `attachments_mut()` methods, giving the type access to all the default
/// methods in the `Attachable` trait.
