Follow the steps to implement this recipe:

1. Open the main.rs file in the src directory in your preferred text editor.
2. Write the code header with the relevant information:

        //-- #########################
        //-- Task: glob experiments
        //-- Author: Vigneshwer.D
        //-- Version: 1.0.0
        //-- Date: 04 May 17
        //-- ######################### 

3. Create the error_chain! macro to define a custom Error and Result type, along with automatic conversions from the standard library error types, after the code header:

        #[macro_use]
        extern crate error_chain;
        error_chain! {
          foreign_links {
            Glob(glob::GlobError);
            Pattern(glob::PatternError);
          }
        }

4. Define the run method and the quick_main! macro by copying and pasting the following code snippet with the error_chain! macro:

        extern crate glob;
        use glob::glob;
        fn run() -> Result<()> {
          for entry in glob("**/*.png")? {
            println!("{}", entry?.display());
          }
          Ok(())
        }
        quick_main!(run);

5. Save the file and run the project by running the following command:

      cargo run

We should get the following output on execution of the code:
