Package Exports

as-variant

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (as-variant) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Variant Data Type for AssemblyScript

Supports any builtin types like i32, bool, string and any custom classes.

Basic Usage

import { Variant } from 'as-variant'

class Foo {}

let vNum = Variant.from(123)      // stored as i32
let vStr = Variant.from('hello')  // stored as string
let vFoo = Variant.from(new Foo())  // stored as string

vNum.set(2.0)                     // now stored as f64

assert(vNum.is<f64>() == true)    // ok
assert(vStr.is<f64>() == false)   // ok
assert(vStr.is<string>() == true) // ok

let valF64 = vNum.get<f64>()      // safely extract value
let tryStr = vNum.get<string>()   // will throw exception!

Use as value for Any Dynamic Dictionary

const dict = new Map<string, Variant>();

dict.set('str', Variant.from('hello'))
dict.set('num', Variant.from(124.0))

dict.set('arr', Variant.from([1, 2, 3]))

assert(dict.get<i32[]>('arr')[2] == 3);

which equivalent to JavaScript:

const dict = {
  str: 'hello',
  num: 124.0
}

dict.arr = [1, 2, 3]

assert(dict.arr[2] == 3);
