Function vrd::run

pub fn run() -> Result<(), Box<dyn Error>>

The main entry point for the Random (VRD) library.

This function performs initial setup and checks before the library can be used. It also provides a basic interface for interacting with the library.

Returns

• Ok(()) if the library initializes successfully.
• Err(Box<dyn std::error::Error>) if there is an error during initialization.

Examples

use vrd::random::Random;
if let Err(e) = vrd::run() {
    println!("Error initializing Random (VRD) library: {}", e);
}

Errors

• Returns a simulated error if the environment variable VRD_TEST_MODE is set to “1”. This is typically used for testing purposes.

Notes

• The function prints a welcome message and a brief description of the library.
• It checks for the VRD_TEST_MODE environment variable to simulate an error, which can be useful for testing error handling in applications using this library.
