Reduced example:

fn ice_on_inference_failure(_: impl Into<i32>) {}

fn test() {
    let s: &str = clap::Command::new("").get_matches().value_of("").unwrap();
    let p = s.parse().unwrap();
    ice_on_inference_failure(p);
}

https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=5bc8ef48088f6050b939796574e95a99

I can't get it to ICE if the clap::ArgMatches nor even clap::Command is passed in as an argument to the test function.

@compiler-errors compiler-errors changed the title Bug connected with probably ambiguous data type when parsing string into i32 from &str from clap - fixed easily, however Cargo told me to post it here Bug connected with probably ambiguous data type when parsing string into i32 from &str from clap Jun 10, 2022
