avail-rust-client 0.5.1

# Avail Rust

**Avail Rust is a Rust library for communicating with Avail networks.**

## In Action

This example uses the [Tokio](https://crates.io/crates/tokio) runtime, but you
can use any runtime you like. Your `Cargo.toml` file could look like this:

```toml
[dependencies]
avail-rust-client = { version = "0.4.0-rc.3", default-features = false, features = ["native", "reqwest"] }
tokio = { version = "1.45.0", features = ["rt-multi-thread", "macros"] }
```

> [!NOTE]
> For the WASM environment, replace "native" with "wasm".

And then the code:

```rust
use avail_rust_client::prelude::*;

#[tokio::main]
async fn main() -> Result<(), Error> {
	// Establishing a connection
	let client = Client::new(TURING_ENDPOINT).await?;

	// Defining account that will sign future transaction
	let signer = Keypair::from_str("bottom drive obey lake curtain smoke basket hold race lonely fit walk")?;
	// Or use one of dev accounts -> let signer = alice();

	// Transaction Creation
	let submittable = client.tx().data_availability().submit_data("My First Data Submission");

	// Transaction Submission
	let submitted = submittable.sign_and_submit(&signer, Options::new(2)).await?;
	println!(
		"Ext Hash: {:?}, Account Id: {}, Nonce: {}, App Id: {}",
		submitted.ext_hash, submitted.account_id, submitted.options.nonce, submitted.options.app_id
	);

	// Transaction Receipt
	let receipt = submitted.receipt(false).await?;
	let Some(receipt) = receipt else {
		panic!("Oops, looks like our transaction was dropped")
	};
	println!(
		"Block Height: {}, Block Hash: {:?}, Ext Hash: {:?}, Ext Index: {}",
		receipt.block_height, receipt.block_hash, receipt.ext_hash, receipt.ext_index
	);

	let block_state = receipt.block_state().await?;
	match block_state {
		BlockState::Included => println!("Block Not Yet Finalized"),
		BlockState::Finalized => println!("Block Finalized"),
		BlockState::Discarded => println!("Block Discarded"),
		BlockState::DoesNotExist => println!("Block Does not Exist"),
	};

	Ok(())
}
```

## Feature Flags

The library is designed to use only the necessary dependencies, so by using
`default-features = false, features = []`, the library will not compile unless
you choose either the `native` or `wasm` target.

After that, you are free to choose one or all of the following feature flags:

- `reqwest`: Sets up a basic RPC client for sending and receiving network data.
  If you’re unsure what this means, it’s best to add this feature flag to your
  list.
- `tracing`: Enables logging/tracing, which is useful when dealing with nonce
  and other transaction-related issues. The logging output can be set to JSON
  format if needed.

## Examples

All existing and new examples can be found
[here](https://github.com/availproject/avail-rust/tree/main/client/examples). They
cover most basic needs and interactions with the chain. If there is something
you need that isn’t covered, let us know—we might add it. :)

## Logging/Tracing

To enable tracing, use the `tracing` feature flag and call
`Client::init_tracing(boolean)` in your code, where `boolean` is `true` or
`false` depending on whether you want to enable JSON-format structured logging.

Example:

```toml
[dependencies]
avail-rust-client = { version = "0.4.0-rc.3", default-features = false, features = ["native", "reqwest", "tracing"] }
tokio = { version = "1.45.0", features = ["rt-multi-thread", "macros"] }
```

```rust
use avail_rust_client::prelude::*;

#[tokio::main]
async fn main() -> Result<(), Error> {
    Client::init_tracing(false)?;
    let client = Client::new(LOCAL_ENDPOINT).await?;
    ...
}
```

After everything is set up run the following command:

```bash
RUST_LOG=info cargo run
```

## Getting Help

In the `avail-rust` repository, we have many examples showing how to use this
library. If something is missing or unclear, don't hesitate to open a

Thank you for your interest in improving this project! As we are still adding
new features and finalizing existing ones, it would be helpful to first post
