capnpc-rust was calling panic!(), but I couldn't see what file it was trying to open. I think this patch will help others.

$ git diff diff --git a/src/codegen.rs b/src/codegen.rs index 16c9be7..93c8f11 100644 --- a/src/codegen.rs +++ b/src/codegen.rs @@ -1596,7 +1596,7 @@ pub fn main(mut inp : T) -> ::std::io::Result<()> use std::io::Write; try!(writer.write_all(text.as_bytes())); }

• Err(e) => {panic!("could not open file {:?} for writing: {}", filepath, e)} } } Ok(())
