Constructors

NativeBuffer(int, bool, TTracker)

public NativeBuffer(int elementCount, bool zeroFill = true, TTracker tracker = default)

Parameters

elementCount int

Number of elements.

zeroFill bool

If true, the buffer is zeroed. Set to false if the caller will initialize the entire span itself.

tracker TTracker

Allows native allocation sizes to be tracked and affect the GC.

public Span<byte> ByteSpan { get; }

Property Value

Span<byte>

Length

Number of TItem elements that fit in the buffer.

public int Length { get; }

Property Value

int

Span

Gets a Span<T> over the native buffer.
