package configs

// A Config is a node in the tree of modules within a configuration.
//
// The module tree is constructed by following ModuleCall instances recursively
// through the root module transitively into descendent modules.
//
// A module tree described in *this* package represents the static tree
// represented by configuration. During evaluation a static ModuleNode may
// expand into zero or more module instances depending on the use of count and
// for_each configuration attributes within each call.
type Config struct {
	// RootModule points to the Config for the root module within the same
	// module tree as this module. If this module _is_ the root module then
	// this is self-referential.
	Root *Config

	// ParentModule points to the Config for the module that directly calls
	// this module. If this is the root module then this field is nil.
	Parent *Config

	// ChildModules points to the Config for each of the direct child modules
	// called from this module. The keys in this map match the keys in
	// Module.ModuleCalls.

	// Elements points to the object describing the configuration for the
	// various elements (variables, resources, etc) defined by this module.
