How to pass command line arguments when using cargo run?

−0

When developing a rust program you build and run using cargo run. However you cannot just append arguments to that as they will be caught (and likely rejected) by cargo itself. So how to pass arguments through cargo run to the actual program under development?

Specify your arguments after --:

cargo run --offline -- --my-argument 42

--offline is just an example of cargo's own argument. They are passed before --.

--my-argument and 42 will be passed to your program.
