Skytable client

Introduction
This library is the official client for the free and open-source NoSQL database Skytable. First, go ahead and install Skytable by following the instructions here. This library supports all Skytable versions that work with the Skyhash 1.1 Protocol. This version of the library was tested with the latest Skytable release (release 0.7.6).
Features
- Sync API
- Async API
- TLS in both sync/async APIs
- Connection pooling for sync/async
- Use both sync/async APIs at the same time
- Always up-to-date
Using this library
This library only ships with the bare minimum that is required for interacting with Skytable. Once you have Skytable installed and running, you're ready to follow this guide!
We'll start by creating a new binary application and then running actions. Create a new binary application by running:
cargo new skyapp
Tip: You can see a full list of the available actions here.
First add this to your Cargo.toml
file:
skytable = "0.7.5"
Now open up your src/main.rs
file and establish a connection to the server while also adding some
imports:
use skytable::{Connection, Query, Element};
fn main() -> std::io::Result<()> {
let mut con = Connection::new("127.0.0.1", 2003)?;
Ok(())
}
Now let's run a Query
! Change the previous code block to:
use skytable::{error, Connection, Query, Element};
fn main() -> Result<(), error::Error> {
let mut con = Connection::new("127.0.0.1", 2003)?;
let query = Query::from("heya");
let res: String = con.run_query(&query)?;
assert_eq!(res, "HEY!");
Ok(())
}
Running actions
As noted below, the default table is a key/value table with a binary key
type and a binary value type. Let's go ahead and run some actions (we're assuming you're
using the sync API; for async, simply change the import to use skytable::actions::AsyncActions
).
SET
ting a key
use skytable::actions::Actions;
use skytable::sync::Connection;
let mut con = Connection::new("127.0.0.1", 2003).unwrap();
con.set("hello", "world").unwrap();
This will set the value of the key hello
to world
in the default:default
entity.
GET
ting a key
use skytable::actions::Actions;
use skytable::sync::Connection;
let mut con = Connection::new("127.0.0.1", 2003).unwrap();
let x: String = con.get("hello").unwrap();
assert_eq!(x, "world");
Way to go — you're all set! Now go ahead and run more advanced queries!
Binary data
The default:default
keyspace has the following declaration:
Keymap { data:(binstr,binstr), volatile:false }
This means that the default keyspace is ready to store binary data. Let's say
you wanted to SET
the value of a key called bindata
to some binary data stored
in a Vec<u8>
. You can achieve this with the RawString
type:
use skytable::actions::Actions;
use skytable::sync::Connection;
use skytable::types::RawString;
let mut con = Connection::new("127.0.0.1", 2003).unwrap();
let mybinarydata = RawString::from(vec![1, 2, 3, 4]);
assert!(con.set("bindata", mybinarydata).unwrap());
Going advanced
Now that you know how you can run basic queries, check out the actions
module documentation for learning
to use actions and the types
module documentation for implementing your own Skyhash serializable
types. Need to meddle with DDL queries like creating and dropping tables? Check out the [ddl
] module.
You can also find some examples here
Connection pooling
This library supports using sync/async connection pools. See the pool
module-level documentation for examples
and information.
Async API
If you need to use an async
API, just change your import to:
skytable = { version = "0.7.2", features=["aio"], default-features = false }
You can now establish a connection by using skytable::AsyncConnection::new()
, adding .await
s wherever
necessary. Do note that you'll the Tokio runtime.
Using both sync
and async
APIs
With this client driver, it is possible to use both sync and async
APIs at the same time. To do
this, simply change your import to:
skytable = { version="0.7.2", features=["sync", "aio"] }
TLS
If you need to use TLS features, this crate will let you do so with OpenSSL.
Using TLS with sync interfaces
skytable = { version="0.7.2", features=["sync","ssl"] }
You can now use the async sync::TlsConnection
object.
Using TLS with async interfaces
skytable = { version="0.7.2", features=["aio","aio-ssl"], default-features=false }
You can now use the async aio::TlsConnection
object.
Packed TLS setup
If you want to pack OpenSSL with your crate, then for sync add sslv
instead of ssl
or
add aio-sslv
instead of aio-ssl
for async. Adding this will statically link OpenSSL
to your crate. Do note that you'll need a C compiler, GNU Make and Perl to compile OpenSSL
and statically link against it.
MSRV
The MSRV for this crate is Rust 1.39. Need const generics? Add the const-gen
feature to your
dependency!
