// Regression test for this example from #31997 -- main goal is to // emit as minimal and precise an error set as possible. Ideally, we'd // only emit the E0433 error below, but right now we emit two. use std::io::prelude::*; // use std::collections::HashMap; use std::io; #[derive(Debug)] struct Instance { name: String, start: Option, end: Option, } fn main() { let input = io::stdin(); let mut input = input.lock(); let mut map = HashMap::new(); //~^ ERROR E0433 for line in input.lines() { let line = line.unwrap(); println!("process: {}", line); let mut parts = line.splitn(2, ":"); let _logfile = parts.next().unwrap(); let rest = parts.next().unwrap(); let mut parts = line.split(" [-] "); let stamp = parts.next().unwrap(); let rest = parts.next().unwrap(); let words = rest.split_whitespace().collect::>(); let instance = words.iter().find(|a| a.starts_with("i-")).unwrap(); let name = words[1].to_owned(); let mut entry = map.entry(instance.to_owned()).or_insert(Instance { name: name, start: None, end: None, }); if rest.contains("terminating") { assert!(entry.end.is_none()); entry.end = Some(stamp.to_string()); } if rest.contains("waiting for") { assert!(entry.start.is_none()); entry.start = Some(stamp.to_string()); } } println!("{:?}", map); }
