Function mini_functions::random::run

source · 
pub fn run() -> Result<(), Box<dyn Error>>
Expand description

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;
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.
