I have an alternative to StrPack.jl here: https://github.com/tbreloff/CTechCommon.jl/blob/master/src/macros.jl. If you have a type that mimics a c-struct, you can create like:
@packedStruct immutable MyStruct field1::UInt8 field2::Byte end and it creates some methods: read, reinterpret, etc which can convert raw bytes into the immutable type. I've only used it on very specific types of data, but it may work for you.
