Compiler panic #40760
Description
I'm a rust-noob. When compiling my experiments, I get a compiler-panic and it asked me to report here.
I tried this code:
// This probably own't work - I added the "inputs::" myself for reference what is taken below.
pub struct inputs::Element {
pub source: String,
pub date: String,
pub name: String,
}
pub fn new(path: String, inform: Sender<inputs::Element>){
loop {
let paths = match fs::read_dir(&path).unwrap(){
fs::ReadDir(r) => r,
_ => panic!("Got error while reading {}", &path)
};
for p in paths {
let pa = p.unwrap().path();
let name = String::from(pa.to_str().unwrap());
let e = inputs::Element{source: String::from("file:") + &path,
date: String::from("Constant"), name: name};
inform.send(e).unwrap();
}
thread::sleep(time::Duration::new(1,0));
}
}I expected to see this happen: ponies - it compiles!
Instead, this happened:

note: the compiler unexpectedly panicked. this is a bug.
