## Changes * Improves type hashing by introducing xxHash3 (64bit) * Removes individual `tdb` files in favor of a single `SerializedTypes.db` file. This file is only used to identify a type that is being deserialized, which doesn't exist. * Adds duplicate type alias detection * Adds `AssemblyHandler.FindTypeByHash` View changed files whitespaces: https://github.com/modernuo/ModernUO/pull/1172/files?diff=split&w=1 ## SerializedTypes.db The serialized types file is used to get back the original name of a type in case it no longer exists in code. This can easily be necessary if a class is renamed in code and no `TypeAlias` is provided. ### Format byte[4] - version byte[4] - count --array-- byte[8] - xxHash byte[1] - flag, 0 - null, 1 - not null byte[n] - Full class name in UTF8 ### Example <img width="472" alt="SerializedTypes_Example" src="https://user-images.githubusercontent.com/3953314/195255429-31d24293-6bd1-419e-811b-07874dd0f78d.png"> ## Benchmarks Serialized 500 Type fields. The 8192bytes comes from the _ConcurrentQueue_ that would later be used for SerializedTypes. Note that the queue is never cleared, so it's size grew considerably. ```cs | Method | Mean | Error | StdDev | Allocated | |--------------------- |---------:|---------:|---------:|----------:| | BenchmarkXXHash | 18.44 us | 0.278 us | 0.260 us | 8192 B | | BenchmarkTypeStrings | 25.09 us | 0.292 us | 0.259 us | - | ``` TODO: * Add support in the Serialization Generator for `ReadType()` and `Write(Type)` * Remove `SetTypeRef` from Serialization Generator
