helschema

helschema

A collection of tools for specifying network protocols in heldb.

example

const HelStruct = require('helschema/struct');
const HelString = require('helschema/string');
const HelFloat = require('helschema/float64');
const HelInt = require('helschema/int32');
const HelDictionary = require('helschema/dictionary');

const Entity = HelStruct({
    x: HelFloat(),
    y: HelFloat(),
    dx: HelFloat(),
    dy: HelFloat(),
    hp: HelInt(10),
    name: HelString('entity')
})

const EntitySet = HelDictionary(Entity)


const entities = EntitySet.alloc()

const player = Entity.create()
player.x = 10
player.y = 10
player.dx = -10
player.dy = -20
player.name = 'player'

entities['foo'] = player

features

• binary serialization
• automated testing
• diff speed benchmark
• patch speed benchmark
• patch size benchmark
• memory pool stats

more types

• fixed point numbers
• enums
• tuples
• fixed size vectors
• variable length arrays
• multidimensional arrays

design

• should models define constructors?
