core_collections
v0.3.20170409 GrowingThis 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.
