Documentation

quicknode-sdk (Rust)

The core Rust crate for the Quicknode SDK.

This is one of four language bindings published from the same Rust core. See the project README for the polyglot overview, development setup, and release process.

Table of Contents

Installation

cargo add quicknode-sdk

Quick Start

Construct the SDK once, then reach into the four sub-clients (admin, streams, webhooks, kvstore). Subsequent API Reference snippets assume you have a qn handle from one of these blocks.

// Rust
use quicknode_sdk::{QuicknodeSdk, SdkFullConfig};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let qn = QuicknodeSdk::from_env()?;
    let resp = qn.admin.get_endpoints(&Default::default()).await?;
    println!("{} endpoints", resp.data.len());
    Ok(())
}

Configuration

There are two ways to configure the SDK.

Option A — Pass config directly

// Rust
let qn = QuicknodeSdk::new(&SdkFullConfig::builder().api_key("your-key").build())?;

Option B — Load from environment (from_env())

// Rust
let qn = QuicknodeSdk::from_env()?;

Environment variables (prefix QN_SDK__, separator __):

Variable Required Default Description
QN_SDK__API_KEY yes — Your Quicknode API key
QN_SDK__HTTP__TIMEOUT_SECS no 30 HTTP request timeout in seconds
QN_SDK__HTTP__POOL_MAX_IDLE_PER_HOST no — Max idle HTTP connections per host
QN_SDK__ADMIN__BASE_URL no https://api.quicknode.com/v0/ Override admin API base URL (HTTPS, must end with /)
QN_SDK__STREAMS__BASE_URL no https://api.quicknode.com/streams/rest/v1/ Override streams base URL
QN_SDK__WEBHOOKS__BASE_URL no https://api.quicknode.com/webhooks/rest/v1/ Override webhooks base URL
QN_SDK__KVSTORE__BASE_URL no https://api.quicknode.com/kv/rest/v1/ Override KV store base URL

API Reference

Snippets assume qn was already constructed via the Quick Start. Optional parameters are skipped unless showing one is needed to illustrate usage.

Language conventions

  • Methods are async and return Result<T, SdkError>. Request structs use the bon builder pattern via ::builder().

Admin Client

Accessed as qn.admin. Manages endpoints, tags, teams, billing, usage, metrics, security, and rate limits. Backed by https://api.quicknode.com/v0/.

Endpoint Rate Limits

update_rate_limits / updateRateLimits

Streams Client

Accessed as qn.streams. Creates and manages blockchain data streams that deliver filtered on-chain events to configured destinations. Backed by https://api.quicknode.com/streams/rest/v1/.

Datasets, Regions, and Destinations

Enums used across stream methods:

  • StreamRegion: UsaEast, EuropeCentral, AsiaEast (wire values: usa_east, europe_central, asia_east).

  • Rust: DestinationAttributes::Webhook(WebhookAttributes { .. }) etc.
  • Python: StreamWebhookDestination(WebhookAttributes(...)), StreamS3Destination(S3Attributes(...)), etc.
  • Node.js: a discriminated object { destination: "webhook", attributes: { ... } } using string discriminators.
  • Ruby: factory methods on QuicknodeSdk::DestinationAttributes, e.g. QuicknodeSdk::DestinationAttributes.webhook(url: ..., ...).

Streams methods

create_stream / createStream

Creates a new stream that delivers filtered data to the configured destination. Start from a specific block for backfills or from the tip for real-time streaming. Supports filters, reorg handling, distance-from-tip, elastic batching, notification emails, and extra destinations.

Parameters: CreateStreamParams — required: name, region, network, dataset, start_range (i64), end_range (i64, -1 = follow tip), destination_attributes, plan, threshold_fetch_buffer. Common optional fields: dataset_batch_size, include_stream_metadata, fix_block_reorgs, keep_distance_from_tip, elastic_batch_enabled, filter_function, filter_language, status, notification_email, extra_destinations.

Returns: Stream.

Error Handling

Every binding exposes a typed exception hierarchy derived from the core SdkError enum (crates/core/src/errors.rs). Catch the base class (SdkError) for any SDK-originated failure, or a specific subclass to branch on transport vs. API semantics.

Logical class When it fires Extra fields
QuicknodeError base class; catches everything below —
ConfigError invalid config or URL surfaced at construction time —
HttpError transport failure that isn't a timeout/connect —
TimeoutError request timed out (subclass of HttpError) —
ConnectionError connection refused / DNS / TLS (subclass of HttpError) —
ApiError non-2xx HTTP response status, body
DecodeError 2xx response but JSON parse failed body

Variants: pattern-match on SdkError { Http, Api, Decode, UrlParse, Config }; use err.http_kind() to classify Http into Timeout, Connect, or Other.

// Rust
match qn.admin.show_endpoint("missing").await {
    Ok(resp) => println!("{:?}", resp.data),
    Err(SdkError::Api { status, body }) if status.as_u16() == 404 => {
        eprintln!("not found: {body}")
    }
    Err(e) if matches!(e.http_kind(), Some(HttpKind::Timeout)) => eprintln!("timed out"),
    Err(e) => eprintln!("other: {e}"),
}
