[erlang-questions] Binary matching partials
Wed Feb 12 10:48:08 CET 2014
decode(Charset, <<A:6,B:6,C:6,D:6, T/binary>>, Acc)
Match incoming stuff, 3 bytes at a time and put the remainder in T. No
If I get 5 bytes it has issues because it's not on the 3-byte boundary.
Fine ... except ...
1) Match less params...try <<A,B,C,D, T>> then <<A,B,C,D >>, <<A,B,C>>,
<<A,B>> and so on.
2) Match against zeros <<A:6, B:6, 0:6, 0:6>>
3) Match against various combinations of bit-widths and remainder/tails
It seems as if it must match exactly, yet matching against the varying
levels of parameters doesn't seem to work.
I couldn't find anything on Google about this particular matching case.
Thanks in advance!
