Доброго времени суток дорогие читатели, короче в декабре 24 года разбирался в коде рослин, и жутко понравилось то как команда рослин уместила 12 булевых свойств и одно байтовое, в единственное ushort поле. Ну и на основе этого быстренько за месяц создал простенькую библиотеку, авось людям это будет нужно.
Упаковка булевых значений
public partial class BitPackedBools { [BitField] public partial bool Bool1 { get; set; } [BitField] public partial bool Bool2 { get; set; } [BitField] public partial bool Bool3 { get; set; } [BitField] public partial bool Bool4 { get; set; } }В этом случае будет сгенерировано 1 байтовое поле, где первые 4 бита используют булевые свойства, имя поля будет равно свойствам которое использует поле.
Сгенерированный код
partial class BitPackedBools { private byte _Bool1__Bool2__Bool3__Bool4__; public partial bool Bool1 { get { return ((this._Bool1__Bool2__Bool3__Bool4__ >> 0) & (1)) == 1; } set { this._Bool1__Bool2__Bool3__Bool4__ = (byte)(value ? ((this._Bool1__Bool2__Bool3__Bool4__) | (((1 << 1) - 1) << 0)) : (this._Bool1__Bool2__Bool3__Bool4__ & ~(((1 << 1) - 1) << 0))); } } public partial bool Bool2 { get { return ((this._Bool1__Bool2__Bool3__Bool4__ >> 1) & (1)) == 1; } set { this._Bool1__Bool2__Bool3__Bool4__ = (byte)(value ? ((this._Bool1__Bool2__Bool3__Bool4__) | (((1 << 1) - 1) << 1)) : (this._Bool1__Bool2__Bool3__Bool4__ & ~(((1 << 1) - 1) << 1))); } } public partial bool Bool3 { get { return ((this._Bool1__Bool2__Bool3__Bool4__ >> 2) & (1)) == 1; } set { this._Bool1__Bool2__Bool3__Bool4__ = (byte)(value ? ((this._Bool1__Bool2__Bool3__Bool4__) | (((1 << 1) - 1) << 2)) : (this._Bool1__Bool2__Bool3__Bool4__ & ~(((1 << 1) - 1) << 2))); } } public partial bool Bool4 { get { return ((this._Bool1__Bool2__Bool3__Bool4__ >> 3) & (1)) == 1; } set { this._Bool1__Bool2__Bool3__Bool4__ = (byte)(value ? ((this._Bool1__Bool2__Bool3__Bool4__) | (((1 << 1) - 1) << 3)) : (this._Bool1__Bool2__Bool3__Bool4__ & ~(((1 << 1) - 1) << 3))); } } }Флаги + SloutCount
Давайте попробуем сделать имитацию NodeFlagsAndSlotCount
public partial class NodeFlagsAndSlotCount { [BitField] public partial bool IsNotMissing { get; set; } [BitField] public partial bool HasAnnotationsDirectly { get; set; } [BitField] public partial bool FactoryContextIsInAsync { get; set; } [BitField] public partial bool FactoryContextIsInQuery { get; set; } [BitField] public partial bool FactoryContextIsInFieldKeywordContext { get; set; } [BitField] public partial bool ContainsAnnotations { get; set; } [BitField] public partial bool ContainsAttributes { get; set; } [BitField] public partial bool ContainsDiagnostics { get; set; } [BitField] public partial bool ContainsDirectives { get; set; } [BitField] public partial bool ContainsSkippedText { get; set; } [BitField] public partial bool ContainsStructuredTrivia { get; set; } [BitField] public partial bool ExtraFlag { get; set; } [ExtendedBitField(BitsCount = 4, GetterLargeSizeValueName = nameof(GetLargeSlotCount))] public partial int SlotCount { get; set; } public virtual int GetLargeSlotCount() => 255; }Прежде чем покажу что сгенерировалась, расскажу немного про атрибут ExtendedBitField.
-
Он наследуется от
BitField -
Если вдруг значение
SlotCountбольше, чем помещается в 4 бита, то геттер свойства вызываетGetterLargeSizeValueName -
Использование
nameofобязательно, без него генератор не будет работать
GetterLargeSizeValueName может быть:
-
Методом, что обязательно должен возвращать тот же тип что и свойство
-
Другим свойством
-
Полем

Заключение
Ну, по итогу это библиотека, ради библиотеки. Если вдруг пригодиться, скажите как пригодилась ну и поставьте звёздочку в гитхабе.
