Installation

Install the III SDK for Rust

Prerequisites

• Rust 1.85 or later
• Tokio async runtime

Add to your project

Add the III SDK to your Cargo.toml:

[dependencies]
iii-sdk = "0.4.1"
tokio = { version = "1", features = ["macros", "rt-multi-thread"] }
serde_json = "1"

Optional Features

OpenTelemetry Integration

To enable distributed tracing, metrics, and logging with OpenTelemetry:

[dependencies]
iii-sdk = { version = "0.4.1", features = ["otel"] }

The otel feature enables:

• Distributed tracing with W3C Trace Context propagation
• Metrics export (counters, gauges, histograms)
• Structured logging export
• HTTP request instrumentation
• Automatic trace context propagation across function calls

Verify Installation

Create a simple test to verify the SDK is working:

use iii_sdk::III;

#[tokio::main]
async fn main() {
    let iii = III::new("ws://localhost:49134");
    println!("III SDK initialized successfully");
}
