asterdex-sdk 0.1.4

// Integration tests against AsterDex testnet.
//
// Prerequisites:
//   1. Configure `.env` at the repo root (copy from `.env.example`, fill in real credentials).
//   2. Run: `cargo test --test aster_integration -- --include-ignored --test-threads=1`
//
// IMPORTANT: must run with `--test-threads=1`.
// Each test creates its own `RestClient` (and thus its own `Credentials`).
// Parallel tests would produce the same EIP-712 nonce (nonce = unix_seconds * 1_000_000
// counted independently per instance), causing `-4226 Nonce used` rejections.
// Sequential execution ensures monotonically-increasing nonces across all tests.
//
// All tests are marked `#[ignore]` so they don't run in CI by default.
// They perform real network calls against https://fapi.asterdex-testnet.com.
