Installation

Add dango-sdk to a Cargo project.

Requirements

Rust 1.85+ (2024 edition).
A tokio runtime — every network call is async.

Add the dependency

[dependencies]
dango-sdk = { git = "https://github.com/left-curve/left-curve" }
tokio     = { version = "1", features = ["macros", "rt-multi-thread"] }
anyhow    = "1"
futures   = "0.3"

dango-sdk is not yet published to crates.io. Pin the dependency to a tag or commit when running in production:

dango-sdk = { git = "https://github.com/left-curve/left-curve", tag = "vX.Y.Z" }

Features

Feature	Default	Effect
`tracing`	off	Emits `tracing::debug!` events for every GraphQL request, subscription handshake, and subscription id. No public symbols change.

Enable it when wiring the SDK into an app that already uses tracing:

dango-sdk = { git = "...", features = ["tracing"] }

What you get

The crate re-exports everything users need at the root:

use dango_sdk::{
    HttpClient, WsClient, Session, SubscriptionStream, SubscriptionVariables,
    SingleSigner, Secret, Secp256k1, Eip712, Keystore,
    WsError,
};

It also re-exports indexer_graphql_types::*, so subscription and query types — SubscribeBlock, subscribe_block::Variables, accounts::Variables, PageInfo, … — are reachable directly from dango_sdk.

First call — issue a query against a live Dango node.
