mod.rs

Overview

This file acts as a module aggregator and re-exporter within its parent module. It declares two submodules, invalidate_branch and link_parent_child, which encapsulate specific functionalities related to branch invalidation and parent-child linking, respectively. It also selectively re-exports key functions from these submodules to control their visibility and simplify access for other parts of the system.

Modules and Their Roles

`invalidate_branch`

Declared as a public submodule.
Contains the function invalidate_branch.
This function is re-exported publicly, making it accessible to external modules that import this module.
Purpose is inferred as handling operations related to invalidating branches, likely within a data structure or workflow.

`link_parent_child`

Declared as a public submodule.
Contains the function connect.
This function is re-exported with pub(crate) visibility, restricting its accessibility to the current crate only.
Responsible for establishing or managing parent-child relationships, possibly linking nodes or elements in a hierarchical structure.

Re-exports and Visibility

Function	Source Module	Visibility	Description
`invalidate_branch`	`invalidate_branch`	pub (public)	Exposed for use outside the crate.
`connect`	`link_parent_child`	`pub(crate)`	Restricted to internal crate use.

The design choice to expose invalidate_branch publicly while restricting connect internally suggests that branch invalidation is a feature intended for wider use, whereas linking is an internal mechanism.

Interaction with Other System Components

Other modules or components can invoke invalidate_branch directly through this module due to its public re-export.
Internal components within the crate can use connect for managing hierarchical or relational data structures but external consumers cannot access it.
This module serves as a controlled interface to underlying functionalities, promoting encapsulation and modular design.

Implementation Details and Algorithms

The file itself does not contain function implementations; instead, it organizes and exposes functionality implemented in the submodules:

invalidate_branch likely involves algorithms to traverse and mark branches as invalid, possibly affecting cache coherence or state consistency.
connect probably implements logic to link nodes in parent-child relationships, ensuring structural integrity or facilitating navigation.

For algorithmic details and implementation, refer to the submodules invalidate_branch and link_parent_child.

Usage Examples

Using `invalidate_branch`

use some_crate::the_module::invalidate_branch;

fn main() {
    // Invalidate a specific branch in a data structure
    invalidate_branch(branch_id);
}

Using `connect` (within the crate)

use crate::the_module::connect;

fn link_nodes(parent: &Node, child: &Node) {
    connect(parent, child);
}
