dynomite
dynomite makes DynamoDB fit your types (and visa versa)
## Overview
Goals
* ⚡ make writing [dynamodb](https://aws.amazon.com/dynamodb/) applications in [rust](https://www.rust-lang.org/) a productive experience
* 🦀 exploit rust's type safety features
* 👩💻 leverage existing work of the [rusoto](https://github.com/rusoto/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](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Programming.Errors.html)
From this
```rust
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
```rust
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](https://softprops.github.io/dynomite) for how
to get started. Enjoy.
## 📦 Install
In your Cargo.toml file, add the following under the `[dependencies]` heading
```toml
dynomite = "0.10"
```
## 🤸 Examples
You can find some example application code under [dynomite/examples](dynomite/examples)
### DynamoDB local
AWS provides [a convenient way to host a local instance of DynamoDB](https://hub.docker.com/r/amazon/dynamodb-local/) 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](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DynamoDBLocal.UsageNotes.html) listening on port `8000`
```sh
$ 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](dynomite/examples/local.rs)
