Nibbles-streams is a wrapper around nibbles which allows you to create input
and output binary streams with changeable element type and endianness.
An example:
(flexi-streams:with-output-to-sequence (stream)
;; Open little endian nibbles-stream with underlying stream's element-type
(let ((output (make-instance 'nibbles-streams:nibbles-output-stream
:stream stream)))
(write-byte 2 output)
(write-sequence #(1 2 3) output)
;; Change element-type and endianness
(setf (nibbles-streams:nibbles-stream-element-type output)
'(signed-byte 16)
(nibbles-streams:nibbles-stream-endianness output)
:big)
(write-byte 1000 output)
(write-sequence #(-1 -2001 300) output)))
=> #(2 1 2 3 3 232 255 255 248 47 1 44)
The package nibble-streams export two types of streams: nibbles-input-stream
and nibbles-output-stream, accessors nibbles-stream-element-type and
nibbles-stream-endianness and a condition nibbles-stream-error which is
signalled when a wrong element type or endianness is specified.
These element types are supported:
(unsigned-byte 8)(unsigned-byte 16)(unsigned-byte 32)(unsigned-byte 64)(signed-byte 8)(signed-byte 16)(signed-byte 32)(signed-byte 64)
