CommunityToolkit.HighPerformance by: Microsoft

This package includes high performance .NET helpers such as: - Memory2D<T> and Span2D<T>: two types providing fast and allocation-free abstraction over 2D memory areas. - ArrayPoolBufferWriter<T>: an IBufferWriter<T> implementation using pooled arrays, which also supports IMemoryOwner<T>. - MemoryBufferWriter<T>: an IBufferWriter<T>: implementation that can wrap external Memory<T>: instances. - MemoryOwner<T>: an IMemoryOwner<T> implementation with an embedded length and a fast Span<T> accessor. - SpanOwner<T>: a stack-only type with the ability to rent a buffer of a specified length and getting a Span<T> from it. - StringPool: a configurable pool for string instances that be used to minimize allocations when creating multiple strings from char buffers. - String, array, Memory<T>, Span<T> extensions and more, all focused on high performance. - HashCode<T>: a SIMD-enabled extension of HashCode to quickly process sequences of values. - BitHelper: a class with helper methods to perform bit operations on numeric types. - ParallelHelper: helpers to work with parallel code in a highly optimized manner. - Box<T>: a type mapping boxed value types and exposing some utility and high performance methods. - Ref<T>: a stack-only struct that can store a reference to a value of a specified type. - NullableRef<T>: a stack-only struct similar to Ref<T>, which also supports nullable references.
