client-config

Client configuration example

Demonstrates the three idiomatic ways to construct a Dapr Client in Rust:

Constructor	Use when
dapr::Client::new()	Standard sidecar deployment — read everything from env vars.
dapr::Client::from_options(opts)	You need explicit, programmatic configuration.
dapr::Client::connect_with_address(a)	You only need to override the address.

Env vars honored

Variable	Default
DAPR_GRPC_ENDPOINT	(unset) — takes precedence
DAPR_GRPC_PORT	50001
DAPR_API_TOKEN	(unset) — no auth header sent
DAPR_CLIENT_TIMEOUT_SECONDS	5

Run

1. Build the examples:

cargo build --examples

2. Run the example with dapr:

dapr run --app-id=rustapp --dapr-grpc-port 50001 -- cargo run --example client-config
