Streamly.Internal.Data.IsMap.HashMap
Contents
Description
Adds an orphan HashMap instance for the IsMap type class from streamly-core package. This is useful for various combinators that use a map type. We cannot define this in streamly-core as it adds several non-boot library dependencies on streamly-core.
