Rust Command Line Arguments


Rust's standard library does not contain a proper argument parser (unlike argparse in Python), instead preferring to leave this to third-party crates. These examples will show the usage of both the standard library (to form a crude argument handler) and the clap library which can parse command-line arguments more effectively.


  • use std::env; // Import the env module
  • let args = env::args(); // Store an Args iterator in the args variable.
