Description: This is a copy of libstd::collections with all the parts that don't work in
core removed. Most importantly, it provides HashMap and HashSet.
This crate is (mostly) automatically generated from the rust git source. The
version of the source that corresponds to your compiler version will be
selected automatically by the build script.
This depends on the rand crate, so make sure to include that and configure the
no_std feature on it.
