# Hash collections usage:
#
# - Enable `hash-collections` to make use of hash-based collections in `wasmi_collections`.
# - Enable `prefer-btree-collections` to still use btree-based collections even when
#   the `hash-collections` crate feature is enabled.
#
# Note:
#
# - Not enabling `hash-collections` allows `wasmi_collections` to drop lots of
#   hash-based dependencies and thus decrease compilation times significantly.
# - Btree-based collections can be useful for environments without a random source.
#
# Which collections will be used:
#
# `hash-collections` | `prefer-btree-collections` |      usage
# ------------------ | -------------------------- | -------------------
#            false   |                    false   |      btree
#             true   |                    false   |      hash
#            false   |                     true   |      btree
#             true   |                     true   |      btree
