Function from_cli 

pub fn from_cli() -> Result<Targets, Error>

Returns the list of targets supported by the current rustc using CLI.

The list of targets can be iterated over using the iter method:

Example

fn main() {
    let targets = rustc_targets::from_cli().unwrap();
    for (i,target) in targets.iter().unwrap().enumerate() {
        println!("{i}. {target}");
    }
}
