convert between binary and lua, based on luajit.
just use like struct class of Python.
this module is still on developing and do not use it now.
example:
local struct = require 'resty.struct'
local binary, err = struct.pack('HHL', 1, 2, 3)
if not binary then print(err) end
local table, count = struct.unpack('HHL', binary)
if table then
for i = 1, count do
print(table[i])
end
else
print(count) -- error message instead
end
