Bug connected with probably ambiguous data type when parsing string into i32 from &str from clap

[yarenty]

Code

use datafusion::error::Result;
use clap::{Arg, Command};


#[derive(Clone)]
pub struct KafkaConfig {
    pub partitions: i32,
}

impl KafkaConfig {
    pub fn new() -> KafkaConfig {
        KafkaConfig {
            partitions: 1,
        }
    }
    /// Set number of kafka partitions - currently round robin
    pub fn with_partitions(&mut self, partitions: impl Into<i32>) -> &mut KafkaConfig {
        self.partitions = partitions.into();
        self
    }
}

#[tokio::main]
async fn main() -> Result<()> {

    let matches = Command::new("Kafka publisher")
        .version(option_env!("CARGO_PKG_VERSION").unwrap_or(""))
        .about("Datafusion kafka publisher")
        .arg(
            Arg::new("partitions")
                .short('p')
                .long("partitions")
                .help("Number of partitions")
                .takes_value(true)
                .default_value("1"),
        )
        .get_matches();
    
    let partition = matches.value_of("partitions").unwrap();
    // BUG:
    let conf = KafkaConfig::new()
        .with_partitions(partition.parse().unwrap());
    
    Ok(())
}

error: could not compile `kafka_writer`

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.
