WARNING: DO NOT USE THIS FEATURE IF YOU ARE WORKING ON CONSENSUS CODE!*
Provides implementations for more data structures than just Vec and Box. Concretely it will provide parity-codec implementations for many types that can be found in std and/or alloc (nightly).
This feature was mainly introduced after it became clear that pDSL requires it for the sake of usability of its users.

Features from optional dependencies
In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality [may be removed in the future](https://rust-lang.github.io/rfcs/3491-remove-implicit-features.html).
