<anon>:20:1: 22:2 error: not all trait items implemented, missing: `next` [E0046]
<anon>:20 impl<'a, V:'a> Iterator for ReadonlyIter<'a,V> {
<anon>:21     type Item = &'a V;
<anon>:22 }
<anon>:20:1: 22:2 help: see the detailed explanation for E0046
error: aborting due to previous error
playpen: application terminated with error code 101

Compilation failed.

I see two links to "E0046" description. If would be helpful if <anon>:NN also were links.

I think #143 does what you want. I need to tidy it up a bit, sorry about the delay.

[jonas-schievink]

Done in #192

Yay!

I wonder if this needs to be fixed when this gets in rust-lang/rust#33240
(I haven't looked into it.)
