Rust SDK

The Rust SDK (pole_rust) connects applications to Lattice Hub without a data-plane proxy. Clients talk to discovery and config gRPC ports and evaluate routing/load-balancing locally.

Install

[dependencies]
pole_rust = "0.2.0"

Requires Rust >= 1.63.0.

Configuration

Defaults to ./pole.yaml / ./pole.yml, or POLE_RUST_CONFIG. Point global.serverConnectors.discover at 8091 and config at 8093. See tests/data/default-config.yml in the SDK repo.

Minimal discovery flow

Repository examples:

• examples/discover.rs — Provider register, Consumer get/watch/get_one_instance
• examples/config.rs — create, publish, and watch configuration files

let ctx = Arc::new(SDKContext::default()?);
let provider = new_provider_api_by_context(ctx.clone())?;
let consumer = new_consumer_api_by_context(ctx)?;
// provider.register(...).await
// consumer.get_one_instance(...).await

Verification

cargo test
cargo run -p e2e_tests -- \
  --console-url http://127.0.0.1:8080 \
  --client-addr 127.0.0.1:8091
