I think Rust is harder to learn, but once you grok it, I don't think it's harder to use, or at least to use correctly. It's hard to write correct C because the standard tooling doesn't give you much help beyond `-Wall`. Rust's normal error messages are delightfully helpful. For example, I just wrote some bad code and got:

    --> src/main.rs:45:34
     |
  45 |         actions.append(&mut func(opt.selected));
     |                             ---- ^^^^^^^^^^^^ expected `&str`, found `String`
     |                             |
     |                             arguments to this function are incorrect
     |
  help: consider borrowing here
     |
  45 |         actions.append(&mut func(&opt.selected));
     |

I even had to cheat a little to get that far, because my editor used rust-analyzer to flag the error before I had the chance to build the code.

Also, I highly recommend getting into the habit of running `cargo clippy` regularly. It's a wonderful tool for catching non-idiomatic code. I learned a lot from its suggestions on how I could improve my work.
