## Prerequsites

* [Install Rust > 1.40](https://www.rust-lang.org/tools/install)

## Usage

```toml
[dependencies]
dapr = "0.12.0"
```

A client can be created as follows:

```rust
use dapr;

async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Get the Dapr port and create a connection
    let port: u16 = std::env::var("DAPR_GRPC_PORT")?.parse()?;
    let addr = format!("https://127.0.0.1:{}", port);

    // Create the client
    let mut client = dapr::Client::<dapr::client::TonicClient>::connect(addr).await?;
```

## Try out examples

[Examples](./examples)

## Building

To build

```bash
cargo build
```

>Note: The proto buf client generation is built into `cargo build` process so updating the proto files under `dapr/` is enough to update the proto buf client.

## To refresh .proto files from upstream dapr

1. Just need to run update-protos.sh, which will basically fetch latest proto updates.
2. By default, it picks from master proto. To specify a particular release/version, please specify with a -v flag

```bash
./update-protos.sh -v v1.10.1
```
