So, I'm writing a byte array (`seq[byte]`) to a FileStream.
Initially, I went for:
f.write(len(barr) # write length of bytearray
for b in barr: # write bytes one by one
f.write(b)
Run
which looks unnecessarily verbose and inefficient.
So, I decided to write/read it as data:
# writing bytearray to stream
f.write(len(fbarr)) # write length of bytearray
f.writeData(addr(barr[0]), barr.len) # write the whole block of barr bytes,
at once
# reading bytearray back from stream
var sz: int
f.read(sz) # read length of bytearray
var barr = newSeq[byte](sz)
discard f.readData(addr(barr[0]), sz) # read the whole block of barr bytes,
at once
Run
It seems to be working fine, but I feel kind-of insecure about it.
Do you see anything wrong with my approach? How would you handle it?
