Rust Borrow Rules Overview

NOTE: The rules shown here do not take the lifetime constraints into account. The rules could be easily adapted to cover the lifetimes as well but this is not done for similicty at this point.

How to read the following:

The operations on the objects and fiels are denoted as follows:

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?
    
    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
        // Override point for customization after application launch.

import { Component } from "React";

export var Enhance = ComposedComponent => class extends Component {
  constructor() {
    this.state = { data: null };
  }
  componentDidMount() {
    this.setState({ data: 'Hello' });
  }
  render() {

To change a field name in django 1.7+

1.  Edit the field name in the model (but remember the old field name: you need it for step 3!)
2.  Create an empty migration
$ python manage.py makemigrations --empty myApp
3.  Edit the empty migration (it's in the migrations folder in your app folder, and will be the most recent migration) by adding

migrations.RenameField('MyModel', 'old_field_name', 'new_field_name'),

to the operations list.

Testable JavaScript Resources

Testing JavaScript isn't just a thing you can read about in children's fairy tales.

This is just a scratch pad of everything I find. As the really good resources start to float to the top, I'll transition them to a more permanent GitHub repo.

General

• Test-Driven JavaScript Development [book]
• JavaScript Testing Recipes [book]
