Implementation of HashMap and HashSet for no_std environments

This crate is deprecated, use hashbrown instead.

hashmap_core

This crate provides an implementation of HashMap and HashSet which do not depend on the standard library and are suitable for no_std environments.

This crate uses the FNV instead of SipHash for the default hasher, because the latter requires a source of random numbers which may not be available in no_std environments.

This crate is nightly-only for now since it uses the alloc crate, which is unstable.
