## MemoryExtensions 　

High performance buffer types such as `IArrayOwner`, `RecyclableBufferWriter`, `ResizableBufferWriter`, `MemoryBufferWriter`, `BufferReader`

```

```

### ArrayPool & IArrayOwner

```

var arrayOwner = ArrayPool.Rent(10);

// var arrayOwner = ArrayPool.Shared.RentArrayOwner(10);

for (var i = 0; i < arrayOwner.Length; i++)

{

    arrayOwner.Array[i] = (byte)i;

}

// return the array to pool

arrayOwner.Dispose();

```

 

### RecyclableBufferWriter

```

var writer = new RecyclableBufferWriter(4);

writer.Write((byte)1);

writer.Write(new byte[] { 2, 3, 4 });

writer.WriteBigEndian(int.MaxValue);           

var writtern = writer.WrittenSpan; // 1,2,3,4,127,255,255,255

// return the buffer to pool

writer.Dispose();

``` 

### ResizableBufferWriter

```

var writer = new ResizableBufferWriter(4);

writer.Write((byte)1);

writer.Write(new byte[] { 2, 3, 4 });

writer.WriteBigEndian(int.MaxValue);           

var writtern = writer.WrittenSpan; // 1,2,3,4,127,255,255,255

``` 

### MemoryBufferWriter & BufferReader

```

var array = new byte[16];

var writer = array.CreateWriter();

// var writer = new MemoryBufferWriter(array);

writer.WriteBigEndian(18);

writer.WriteBigEndian(2.01f);

var reader = new BufferReader(array);

reader.ReadBigEndian(out int v1);

reader.ReadBigEndian(out float v2);

```

    

### IMemoryOwner Slice 

```

var owner = MemoryPool.Shared.Rent(10);

new byte[] { 1, 2, 3, 4 }.CopyTo(owner.Memory.Span);

var sliced = owner.Slice(0, 2); // 1,2

// return the memory to pool

sliced.Dispose();

```
