# Description This clone is not necessary and tanks the performance of deep nested access. As soon as we found the value, we know we discard the old value, so can `std::mem::take` the inner (`impl Default for Value` to the rescue) We may be able to further optimize this but not having to clone the value is vital.
nu-protocol
The nu-protocol crate holds the definitions of structs/traits that are used throughout Nushell. This gives us one way to expose them to many other crates, as well as make these definitions available to each other, without causing mutually recursive dependencies.
