I was using the latest version of quick-error and tried to store a reference without a lifetime annotated in a macro-generated error. This shouldn't (and doesn't) work, but rustc should at least throw an error instead of blowing up, right?
Code sample:
use quick_error::quick_error;
quick_error! {
pub enum AReferenceInQuickError {
CrashesRustc(s: &str) {
display("hello, {}!", s)
}
}
}
fn main() {
let world = "world";
AReferenceInQuickError::CrashesRustc(world);
}I expected an error of some sort about lifetimes or macros, but instead, the compiler paniced:
thread 'rustc' panicked at 'called `Result::unwrap()` on an `Err` value: DistinctSources(DistinctSources { begin: (Real("src/main.rs"), BytePos(0)), end: (Macros("::quick_error::quick_error"), BytePos(7612215)) })', src/librustc_errors/lib.rs:197:29
