No longer compiles

[BHouwens]

Maintenance on open source stuff is tough, so while I open this issue I also understand that it might not be possible to solve these problems right away and I'm happy to help with a PR if someone can point me in the right direction.

It seems that this library relies on traits in the std and heap libraries that have since been made unstable or deprecated, and as a result it doesn't compile

ramp only works on nightly, see the README:

NOTE Due to use of unstable features (notably inline assembly), Ramp can only be compiled with a nightly build of rustc.

Version 0.3.13 compiles as of Jun 16, 2018. I'm sorry for taking so long to respond to all this.
