Utilities to read/write primitives from/to spans easily. Uses the C# Span struct.

Reading/writing spans can be a chore, keeping track of where you're up to reading a span. This lib lets you simplify this:

var one = BinaryPrimitives.ReadUInt16LittleEndian(span.Slice(3, 2));
var two = BinaryPrimitives.ReadUInt32LittleEndian(span.Slice(5, 4));
var three = BinaryPrimitives.ReadUInt16BigEndian(span.Slice(9, 2));

to this:

int cursor = 0;
var one = span.ReadUInt16LittleEndian(ref cursor);
var two = span.ReadUInt32LittleEndian(ref cursor);
var three = span.ReadUInt16BigEndian(ref cursor);

or:

var spanReader = new SpanReader(span);
var one = spanReader.ReadUInt16LittleEndian();
var two = spanReader.ReadUInt32LittleEndian();
var three = spanReader.ReadUInt16BigEndian();

This lib is based around the System.Buffers.Binary.BinaryPrimitives class, with some other methods sprinkled in for some spice.

• SpanReader for reading a span
• SpanWriter for creating and writing to a span; initialize with size or Memory<byte>
• A tonne of extension methods, applicable to Span<byte> and ReadOnlySpan<byte> - all ripped straight from System.Buffers.Binary.BinaryPrimitives, as well as:
• span.ReadSpan() - same as slice, but keeps track of where you're up to
• span.ReadASCIIString() - does what it says on the packet
• span.ReadUTF8String() - I think you get the drift
