Lib.rs

Summary

This code implements a Rust program that searches for files bigger than 100mb in a given directory or the whole file system if no filepath is given. It uses the clap and std libraries for command line argument parsing and file size calculation, respectively.

Example Usage

// Run the program with a specific directory path
$ ./sizer -p /path/to/directory

// Run the program without specifying a directory path (searches the whole file system)
$ ./sizer

// Run the program with a specific directory path and custom file size threshold
$ ./sizer -p /path/to/directory -s 200

Code Analysis

Inputs

• matches: A clap::ArgMatches object that contains the parsed command line arguments.

Flow

1. Initialize the logger for logging purposes.
2. Parse the command line arguments using clap to get the matches object.
3. Get the value of the path argument from the matches object.
4. If a path value is provided, convert it to a PathBuf object and assign it to home_dir.
5. Get the value of the size argument from the matches object.
6. If a size value is provided, assign it to size as an Option<&String>.
7. If a path value is provided, call the entry function from the sizer library with home_dir and size as arguments.
8. If no path value is provided, create a PathBuf object for the root directory ("/") and assign it to root_dir.
9. Call the entry function from the sizer library with root_dir and size as arguments.

Outputs

None. The function performs file size calculations and logging based on the provided command line arguments.
