Changing the icon of an .exe file in Rust

Question

So I did some research and found out about rs.exe in Windows to convert my resources.rs file containing a name to_do and PATH to ico to res. The only problem is after navigating to its directory and running the command rs resource.exe. I get the error RC1109 which im told is that the rc.exe can not find the path.

What am I doing wrong? should I keep my resources.rs file in the same folder as the rc.exe?

do I have to format the text included in the file in some sort of way?

As always thanks for your help!

You mention rc.exe, but have tagged rs.exe? Overall, are you asking how you can add an icon to your exe, build from `cargo build`? — vallentin, Mar 28 '21 at 08:22

You can use the winres crate to set an icon for the .exe when you run cargo build or cargo run.

Add this to your Cargo.toml:

[package]
...
build = "build.rs"

[build-dependencies]
winres = "0.1"

Then create a build.rs file in the same directory where the Cargo.toml is located, with the following content:

extern crate winres;

fn main() {
  if cfg!(target_os = "windows") {
    let mut res = winres::WindowsResource::new();
    res.set_icon("my_icon.ico"); // Replace this with the filename of your .ico file.
    res.compile().unwrap();
  }
}

Then you have to copy your .ico file in that same directory, too. Don't forget to change the filename in build.rs.

You can try to delete the /target directory and rebuild again. Or try to copy the exe to another location. Sometimes the file explorer caches these icons... – frankenapps Mar 28 '21 at 19:29
Yes I got it to work, thank you man, I don't know if it helped but I added the build.rs to my package in the cargo.toml – IslandPenguin Mar 28 '21 at 19:36
Yes, sorry. Forgot to write this down. Answer is updated. – frankenapps Mar 29 '21 at 07:42
