Borsh-as

borsh-as is an assemblyscript implementation of the borsh serializer.

How to use it

Install the package via yarn add @serial-as/borsh and add the --transform @serial-as/transform flag to your asc command.

import { BorshSerializer, BorshDeserializer } from '@serial-as/borsh'

@serializable
class Pair{
  x: i32 = 0,
  y: i32 = 0
}

let pair: Pair = {x:1, y:2}

// `serialized` is the u8 buffer [0, 0, 0, 1, 0, 0, 0, 2]
let serialized: ArrayBuffer = BorshSerializer.encode(object)  

// `decoded` is the Pair = {x:1, y:2}
let decoded: Pair = BorshDeserializer.decode<Pair>(serialized)  

Limitations

Assemblyscript does not have Enums, nor allows to predefine the length of an array. Because of this, Borsh-as has the following limitations:

• Does not deserialize Enums.
• Does not deserialize fixed-size arrays.
