Create ABI-compliant "union" instances on top of Buffers

Installation

$ npm install ref-union

Examples

var ref = require('ref')
var Union = require('ref-union')

// a couple typedefs
var int = ref.types.int
var float = ref.types.float
var string = ref.types.CString

// define a Union type with 3 data fields
var u_tag = new Union({
    ival: int
  , fval: float
  , sval: string
})

// the size of the union matches the largest data type in the union type
u_tag.size === string.size

// and you can create new instances of the union type
var tag = new u_tag
tag.ival = 5
