Concept for ruby-diesel

diesel.js

var diesel = require("diesel")
var User = require('User');

diesel.config({
  infer_schema = true
  infer_models = true      # I was thinking this would create Queriable structs with sane defaults based on schema
  database_url = "postgres://localhost/ruby_diesel_dev"
  model_mapping: {
    users: User
  }
});

example.js

var diesel = require("diesel")
var usesr_table = diesel.users;

users = users_table.filter(diesel.users_table.first_name.eq(string))
  .limit(1)
  .load()  // would call diesel_load internally with an array of commands/query_fragments?

users // [User]

rust_side.rs

// setup for Neon (or FFI)

fn load(call: Call) -> JsResult<JsString> {
  let commands: Handle<JsArray> = try!(try!(call.arguments.require(scope, 0)).check::<JsArray>());
  let records = build_query!(commands);  // Possible?
  
  // Other fancy stuff
  
  Ok(JsArray::new(scope, records.unwrap())
}

register_module!(m, {
    m.export("load", load)
});

user.js

class User {
  constructor(id, first_name, last_name, email) {
    this.id = id;
    this.first_name = first_name;
    this.last_name = last_name;
    this.email = email;
  }
}

module.exports = User;
