public SpanWriter(byte[] buffer, bool isBigEndian, bool allowNegativeShift)

spanWriter = SpanWriter(buffer, isBigEndian, allowNegativeShift)

Initializes a new instance of the SpanWriter struct.

buffer: The array to write data to.

allowNegativeShift: If true, allows negative Skip to move position backward.

SpanWriter

public SpanWriter(Memory<byte> memory, bool isBigEndian, bool allowNegativeShift)

spanWriter = SpanWriter(memory, isBigEndian, allowNegativeShift)

Initializes a new instance of the SpanWriter struct.

memory: The memory to write data to.
isBigEndian: If true, reads in big-endian order; otherwise, little-endian.
allowNegativeShift: If true, allows negative Skip to move position backward.

SpanWriter

public SpanWriter(Span<byte> span, bool isBigEndian, bool allowNegativeShift)

spanWriter = SpanWriter(span, isBigEndian, allowNegativeShift)

Initializes a new instance of the SpanWriter struct with the specified span.

span: The span to write data to.
isBigEndian: If true, writes in big-endian order; otherwise, little-endian.
allowNegativeShift: If true, allows negative Skip to move position backward.
