constexpr bool	seekable (Whence origin) const
	True if the stream supports seeking from the specified origin.

Result< ByteSpan >	Read (ByteSpan dest)

Result< ByteSpan >	Read (void *dest, size_t size_bytes)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Result< ByteSpan >	ReadExact (ByteSpan const buffer)

Status	Write (ConstByteSpan data)

Status	Write (const void *data, size_t size_bytes)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Status	Write (const std::byte b)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Status	Seek (ptrdiff_t offset, Whence origin=kBeginning)

size_t	Tell ()

size_t	ConservativeReadLimit () const

size_t	ConservativeWriteLimit () const

Private Member Functions
StatusWithSize	DoRead (ByteSpan destination) override
	Virtual Read() function implemented by derived classes.

Status	DoWrite (ConstByteSpan data) override
	Virtual Write() function implemented by derived classes.

Additional Inherited Members
Public Types inherited from pw::stream::Stream
enum	Whence : uint8_t { kBeginning = 0b001 , kCurrent = 0b010 , kEnd = 0b100 }
	Positions from which to seek. More...

Static Public Attributes inherited from pw::stream::Stream
static constexpr size_t	kUnlimited = std::numeric_limits<size_t>::max()
	Value returned from read/write limit if unlimited.

static constexpr size_t	kUnknownPosition = std::numeric_limits<size_t>::max()
	Returned by Tell() if getting the position is not supported.
