PyByteBuffer 1.0.5

A bytes manipulation library inspired by Java ByteBuffer

PyByteBuffer

A library to manipulate buffers inspired by Java nio ByteBuffer

>> DOCUMENTATION

Setup

pip3 install PyByteBuffer

Usage

from PyByteBuffer import ByteBuffer

buf = ByteBuffer.allocate(50)
# write byte 0x10 and increment position by 1
buf.put(0x10)
buf.put([0xcc, 0xdd, 0xee])
buf.put('something')
buf.put(bytes([00] * 4))

# endianness
buf.put(123456, 'little')
buf.put(1234561434234234, 'big')

# read 1 byte and increment position by 1
value = buf.get(1)
# read 10 bytes little endian and increment position by 10
value = buf.get(10, 'little')

# other allocations
buf = ByteBuffer.from_hex('deadbeef')
buf = ByteBuffer.wrap(bytes())

About performances

The performance analysis we can do in this library is all around the conversion between int->bytes bytes<-int.

Tested with a cycle of 1/100/500/1000 conversion using python3 builtin api int.to_bytes/from_bytes, struct pack/unpack and a "primitive" solution posted in stackoverflow
