Password vault in Rust

A CLI project

main.rs:

Module Declaration and Imports:

• The main.rs file declares a module named pentry.

• It imports functions and types from the pentry module, including prompt, read_passwords_from_file, and ServiceInfo.

• Clear Screen Function (clr):

• The clr function is a helper function that clears the terminal screen using ANSI escape sequences.

Main Function:

• The main function serves as the entry point of the program.
• It clears the screen using clr.
• It prints an ASCII art representing the program's title or logo.
• Inside a loop, it presents a menu to the user, prompting for input and executing corresponding actions based on the user's choice.

Menu Choices: For each menu choice:

• If the user chooses to add an entry ("1"), it prompts the user for service, username, and password, creates a ServiceInfo object, and writes it to the file.
• If the user chooses to list entries ("2"), it reads password entries from the file and prints them to the console.
• If the user chooses to search ("3"), it reads password entries from the file, prompts the user for a search term, and prints matching entries to the console.
• If the user chooses to quit ("4"), it prints a goodbye message and breaks out of the loop.

pentry.rs:

ServiceInfo Struct:

• The ServiceInfo struct represents a password entry with fields for service, username, and password.
• It implements methods to create a new entry, deserialize from JSON, serialize to JSON, and write to a file.

File Operations:

• The write_to_file method writes the ServiceInfo object to a file named passwords.json.

• The read_passwords_from_file function reads password entries from the passwords.json file into a vector of ServiceInfo objects.

• The prompt function prompts the user for input and returns the entered string.

• Overall, the program provides a basic command-line interface for managing a password vault, allowing users to add, list, search, and quit operations.
