compile error with nightly rustc

[silvio]

Hi, I have a compile problem with rustc nightly: rustc 1.12.0-nightly (197be89f3 2016-08-15).

error[E0308]: mismatched types

error: Could not compile `vec_map`.

Thanks for the report, which uncovered a bug that was introduced into the standard library. Hopefully it'll be fixed for tomorrow's nightly.

I'm now seeing the same breakage on the beta channel? https://travis-ci.org/cryptosphere/ithos/builds/153177895

Yes, the original problem made it into beta, and the fix hasn't been backported yet. This is not a bug in vec-map.

In rustc 1.13.0-nightly (aef6971ca 2016-08-17) fixed now.
