System.Memory 4.6.3

About

Provides types for efficient representation and pooling of managed, stack, and native memory segments and sequences of such segments, along with primitives to parse and format UTF-8 encoded text stored in those memory segments.

Main Types

The main types provided by this library are:

  • System.Span
  • System.ReadOnlySpan
  • System.Memory
  • System.ReadOnlyMemory
  • System.Buffers.MemoryPool
  • System.Buffers.ReadOnlySequence
  • System.Buffers.Text.Utf8Parser
  • System.Buffers.Text.Utf8Formatter

Additional Documentation

The types in this assembly are shipped as part of the shared framework starting with .NET Core 3.1.

Microsoft.Extensions.Logging.Abstractions
Logging abstractions for Microsoft.Extensions.Logging. Commonly Used Types: Microsoft.Extensions.Logging.ILogger Microsoft.Extensions.Logging.ILoggerFactory Microsoft.Extensions.Logging.ILogger<TCategoryName> Microsoft.Extensions.Logging.LogLevel Microsoft.Extensions.Logging.Logger<T> Microsoft.Extensions.Logging.LoggerMessage Microsoft.Extensions.Logging.Abstractions.NullLogger

System.Collections.Immutable
This package provides collections that are thread safe and guaranteed to never change their contents, also known as immutable collections. Like strings, any methods that perform modifications will not change the existing instance but instead return a new instance. For efficiency reasons, the implementation uses a sharing mechanism to ensure that newly created instances share as much data as possible with the previous instance while ensuring that operations have a predictable time complexity. Commonly Used Types: System.Collections.Immutable.ImmutableArray System.Collections.Immutable.ImmutableArray<T> System.Collections.Immutable.ImmutableDictionary System.Collections.Immutable.ImmutableDictionary<TKey,TValue> System.Collections.Immutable.ImmutableHashSet System.Collections.Immutable.ImmutableHashSet<T> System.Collections.Immutable.ImmutableList System.Collections.Immutable.ImmutableList<T> System.Collections.Immutable.ImmutableQueue System.Collections.Immutable.ImmutableQueue<T> System.Collections.Immutable.ImmutableSortedDictionary System.Collections.Immutable.ImmutableSortedDictionary<TKey,TValue> System.Collections.Immutable.ImmutableSortedSet System.Collections.Immutable.ImmutableSortedSet<T> System.Collections.Immutable.ImmutableStack System.Collections.Immutable.ImmutableStack<T>
