ZString | Zero Allocation StringBuilder for .NET and Unity | Reflection library

You can add https://github.com/Cysharp/ZString.git?path=src/ZString.Unity/Assets/Scripts/ZString to Package Manager. You can install managed DLL from package mangers’s samples Import button. If you want to set a target version, ZString uses the ..* release tag so you can specify a version like #2.4.0. For example https://github.com/Cysharp/ZString.git?path=src/ZString.Unity/Assets/Scripts/ZString#2.4.0. Advanced Tips --- ZString.CreateStringBuilder(notNested:true) is a special optimized parameter that uses ThreadStatic buffer instead of rent from ArrayPool. It is slightly faster but can not use in nested. ZString.CreateStringBuilder() is same as ZString.CreateStringBuilder(notNested:false). In default, SByte, Int16, Int32, Int64, Byte, UInt16, UInt32, UInt64, Single, Double, TimeSpan, DateTime, DateTimeOffset, Decimal, Guid, String, Char are used there own formatter to avoid .ToString() allocation, write directly to buffer. If not exists there list type, used .ToString() and copy string data. If you want to avoid to convert string in custom type, you can register your own formatter. CreateStringBuilder and CreateUtf8StringBuilder must use with using. Because their builder rent 64K buffer from ArrayPool. If not return buffer, allocate 64K buffer when string builder is created. Utf16ValueStringBuilder and Utf8ValueStringBuilder are mutable struct, be careful to copy by passing method. Use ref and try-finally. [TryFormat(DateTime)](https://docs.microsoft.com/en-us/dotnet/api/system.buffers.text.utf8formatter.tryformat?view=netcore-3.1#System_Buffers_Text_Utf8Formatter_TryFormat_System_DateTime_System_Span_System_ByteSystem_Int32System_Buffers_StandardFormat_) and [TryFormat(TimeSpan)](https://docs.microsoft.com/en-us/dotnet/api/system.buffers.text.utf8formatter.tryformat?view=netcore-3.1#System_Buffers_Text_Utf8Formatter_TryFormat_System_TimeSpan_System_Span_System_ByteSystem_Int32System_Buffers_StandardFormat_) symbol is too restricted than standard string format. If you want to use custom format, deconstruct there Day, Hour, etc. Utf8ValueStringBuilder and Utf16ValueStringBuilder implements IBufferWriter so you can pass serializer(such as JsonSerializer of System.Text.Json). But be careful to boxing copy, ValueStringBuilder is mutable struct. For example,. License --- This library is licensed under the MIT License.
