🎉 Update sncast script, add rust node (#254)

* Add starknet devnet rs docs

* Update sncast script: update the regex on declaration output to read class hash

* Update snforge command to snforge test for proper testing

* Update the script to include different lines for reading an already declared classhash for devnet rs and devnet python

-# Starknet Devnet 🚧
+# Starknet Devnet Rust
+
+Starknet Devnet Rust is devnet in rust similar to the [`pythonic devnet`](https://0xspaceshard.github.io/starknet-devnet/docs/intro).
+
+## Installation
+
+There are two ways to install `starknet devnet rs`. You can either use `docker` or clone the repository and `cargo run`.
+
+### Using docker
+
+To use docker, use the procedures highlighted [here](https://github.com/0xSpaceShard/starknet-devnet-rs#readme)
+
+### Using manual procedure (Cloning the repo)
+
+Prerequisites:
+
+- [Rust](https://www.rust-lang.org/tools/install)
+
+Procedure
+
+1. Create a folder where you want to place it.
+
+2. Then run this command
+
+```shell
+git clone [email protected]:0xSpaceShard/starknet-devnet-rs.git
+```
+
+## Running
+
+To run starknet devnet rs after installation run
+
+```rust
+cargo run
+```
+
+Successfull Result
+
+```shell

+Initial balance of each account: 1000000000000000000000 WEI
+Seed to replicate this account sequence: 912753742
+```
+
+### Running Options
+
+1. Using a seed
+
+When you run starknet devnet it gives you a `Seed to replicate this account sequence` meaning you can use the given seed to get the accounts you have used previously making your work easier when using other tools like [`sncast`](https://book.starknet.io/ch02-12-foundry-cast.html) or `starkli` to interact with your contract because you are not going to change the accounts.
+
+To load the old accounts based on a given `seed` run
+
+```shell
+cargo run -- --seed <SEED>
+```
+
+Example
+
+```shell
+cargo run -- --seed 912753742
+```
+
+2. Dumping and loading data
+
+Dumping and loading data will help you to continue working from where you left off.
+
+- To `dump` use the following command
+
+Dumping can be done on `exit` or `transaction`. For our case we have done it on exit.
+
+I have done the dumping into a given `directory` remember to have the directory but not the file.
+
+```shell
+cargo run -- --dump-on exit --dump-path ./dumps/contract_1
+```
+
+- To `load` use the following command and pass in the seed otherwise you will get an error `low account balance`.
+
+On loading, have both the directory and the file existing, the file was automatically created by the `dump` command.
+
+```shell
+cargo run -- --dump-path ./dumps/contract_1 --seed 912753742
+```
+
+> > For more options check [here](https://0xspaceshard.github.io/starknet-devnet/docs/guide/run) though this is the `pythonic devnet`. Only difference is before the first flag have two extra dashes ie `cargo run -- --port 5006` or `cargo run -- -- dump-on exit ...`. The rest of the flags can be passed in normally.
+
+#### Cross-version disclaimer
+
+Dumping and loading is not guaranteed to work cross-version. I.e. if you dumped one version of Devnet, do not expect it to be loadable with a different version.
+
+### Minting
+
+You can mint tokens to an address or a new address using the command below
+
+```shell
+curl -d '{"amount":8646000000000, "address":"0x6e...eadf"}' -H "Content-Type: application/json" -X POST http://localhost:5050/mint
+```
+
+> All commands that work in the [`sncast section`](https://book.starknet.io/ch02-12-foundry-cast.html) and `starkli` work here as well.
+
+## Conclusion
+
+Rust Devnet is faster starting from powering on to handling transactions as compared to pythonic devnet making testing locally much smoother.
