Struct DeduplicatedString 

pub struct DeduplicatedString(pub String);

Wrapper for strings, enabling desert’s string deduplication mode.

The library have a simple deduplication system, without sacrificing any extra bytes for cases when strings are not duplicate. In general, the strings are encoded by a variable length int representing the length of the string in bytes, followed by its UTF-8 encoding. When deduplication is enabled (the string values are wrapped in DeduplicatedString) , each serialized string gets an ID and if it is serialized once more in the same stream, a negative number in place of the length identifies it.

It is not turned on by default because it breaks backward compatibility when evolving data structures. If a new string field is added, old versions of the application will skip it and would not assign the same ID to the string if it is first seen.
