dynomite

dynomite makes DynamoDB fit your types (and visa versa)


Overview

Goals

  • make writing dynamodb applications in rust a productive experience
  • 🦀 exploit rust's type safety features
  • 👩‍💻 leverage existing work of the rusoto rust project
  • commitment to supporting applications built using stable rust
  • 📚 commitment to documentation

Features

  • 💌 less boilerplate
  • ♻️ automatic async pagination
  • 🕶️ client level retry interfaces for robust error handling

From this

use std::collections::HashMap;
use rusoto_dynamodb::AttributeValue;
use uuid::Uuid;

let mut item = HashMap.new();
item.insert(
  "pk".to_string(), AttributeValue {
    s: Some(Uuid::new_v4().to_hyphenated().to_string()),
    ..AttributeValue::default()
  }
);
item.insert(
  // 🤬typos anyone?
  "quanity".to_string(), AttributeValue {
    n: Some("whoops".to_string()),
    ..AttributeValue::default()
  }
);

To this

use dynomite::Item;
use uuid::Uuid;

#[derive(Item)]
struct Order {
  #[dynomite(partition_key)]
  pk: Uuid,
  quantity: u16
}

let item = Order {
  pk: Uuid::new_v4(),
  quantity: 4
}.into();

Please see the API documentation for how to get started. Enjoy.

📦 Install

In your Cargo.toml file, add the following under the [dependencies] heading

dynomite = "0.10"

🤸 Examples

You can find some example application code under dynomite/examples

DynamoDB local

AWS provides a convenient way to host a local instance of DynamoDB for testing.

Here is a short example of how to get up a testing locally quickly with both dynomite as well as rusoto_dynamodb.

In one terminal spin up a Docker container for DynamoDB local listening on port 8000

$ docker run --rm -p 8000:8000 amazon/dynamodb-local

In another, run a rust binary with a client initialized like you see the the local.rs example
