::: firebird.base.buffer options: members: false

MemoryBuffer starts with a capacity and a position of zero. Writes advance pos; set it back to zero before reading the data you wrote. Number reads and writes use the selected byte order:

from firebird.base.buffer import MemoryBuffer
from firebird.base.types import ByteOrder

buffer = MemoryBuffer(4, byteorder=ByteOrder.BIG)
buffer.write_short(0x1234)
buffer.write(b"OK")
assert buffer.pos == 4
assert bytes(buffer.get_raw()) == b"\x12\x34OK"

buffer.pos = 0
assert buffer.read_short() == 0x1234
assert bytes(buffer.read(2)) == b"OK"
assert buffer.pos == 4

get_raw() returns the storage content as bytes or a bytearray regardless of the chosen buffer factory. A buffer's capacity may exceed the amount of data written, so use pos to track where the next read or write takes place.
