New feature

[Nyarum]

Hello, i very grateful for your work.
I have a proposal to introduce - Skip, Endian in structure.

Could you elaborate?

• By skip, do you mean an annotation allowing a field to be skipped?
• The endianness can be changed by setting binary.DefaultEndian, though I realise this isn't ideal.

• Skip (Example)

type S1 struct {
Id int8 skip:"2"
Name string
}

byte[0x04, 0x05, 0x06, 0x5, 0x42, 0x6f, 0x62, 0x62, 0x79]

Result:

S1.Id = 6
S1.Name = Bobby

• Endian (Example)

type S1 struct {
Id int8 Endian:"Big"
Name string Endian:"Little"
}

There are cases when Endian mixed.

Ok, I understand now. What's the use case for these? In general the package isn't designed for reading existing wire formats (eg. it only supports one method of encoding strings - varint length-prefixed), but I'm not sure what else these changes would be useful for?

• Emulation protocols MMORPG games.
• Parsing is not known formats.

Your package is currently closest to the realization of the desired functionality. As soon as I can get to the code, then I will send pull requests.

I think this is a good idea, but perhaps not for this package.
