The [rincon_session] [crate] provides a convenient API for __synchronous__ communication with an
[ArangoDB] server.

The [rincon_session API] is a higher level API on top of the [rincon_client API] and provides
additional features:

* Convenient API for applications to communicate to an [ArangoDB] server. (READY)
<br/>E.g. no need to manually specify the database and collection on each and every request.
* Efficient handling of connections to the [ArangoDB] server (PLANNED)
* Efficient execution of batch operations (PLANNED)
* Convenient API for transaction handling (PLANNED)

Here is an example on how inserting a new document into an existing collection looks like:

```rust
#[derive(Debug, Clone, Serialize, Deserialize)]
struct Customer {
    name: String,
    age: u8,
}

// obtain a session reference for the existing collection named `customers`
let collection = database.use_collection_with_name("customers");

let customer = Customer {
    name: "Jane Doe".to_owned(),
    age: 42,
};

// insert the document and get the document header with document id, key and revision
let document_header = collection.insert_document(customer).unwrap();
```

The [rincon_session] [crate] is part of the [Rincon ArangoDB Rust driver project][Rincon project].

__Note__: A similar but asynchronous API is provided by the [rincon_session_async] crate which is
also part of the [Rincon project].   

## Usage

To use the synchronous session API of this crate add this to your `Cargo.toml`:

```toml
[dependencies]
rincon_core = "0.1"
rincon_connection = "0.1"
rincon_session = "0.1"
```

And this to your crate root:

```rust
extern crate rincon_core;
extern crate rincon_connection;
extern crate rincon_session;
```

__Important__: As [rincon_session] depends on [rincon_client] it re-exports the crate features of
[rincon_client]. Therefore please make sure that you specify the features for [rincon_session] that
are suitable for the setup of your [ArangoDB] server the same way as specified for the
[rincon_client] crate. 

For example to use [rincon_session] with an [ArangoDB] server configured to use RocksDB in a cluster
specify the dependency with features like so:

```toml
[dependencies]
rincon_session = { version = "0.1", default-features = false, features = ["rocksdb", "cluster"] }
```
