⚠ Work in Progress ⚠

Dapr is a portable, event-driven, serverless runtime for building distributed applications across cloud and edge.

• dapr.io
• @DaprDev

Prerequisites

Ensure you have Rust version 1.40 or higher installed. If not, install Rust here.

How to use

Add the following to your Cargo.toml file:

[dependencies]
dapr = "0.13.0"

Here's a basic example to create a client:

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?;

Building

To build the SDK run:

cargo build

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

Updating .proto files from upstream Dapr

To fetch the latest .proto files from Dapr execute the script update-protos.sh:

./update-protos.sh

By default, the script fetches the latest proto updates from the master branch of the Dapr repository. If you need to choose a specific release or version, use the -v flag:

./update-protos.sh -v v1.12.0
