小知识点

一、

<<Length:32/big-unsigned-integer,OneInt/big-unsigned-integer-unit:32,StrLength:16,Left/binary>> = Bin,
  

<<Length:32/big-unsigned-integer,OneInt:1/big-unsigned-integer-unit:32,StrLength:16,Left/binary>> = Bin,            

红色的编辑不过去,erl会提示:a bit unit size must not be specified unless a size is specified too
