Prerequisites

• Rust toolchain (1.75.0 or later)
• .NET SDK 8.0 or later
• Node.js 14.0 or later (for build scripts)
• macOS 10.15 or later

Installation

# Using cargo
cargo add naps2-rust-bindings

# Or add to Cargo.toml
[dependencies]
naps2-rust-bindings = "0.1.0"

Quick Start

use naps2_rust_bindings::{ScanClient, Driver};
use anyhow::Result;

fn main() -> Result<()> {
    // Create a scan client
    let client = ScanClient::new("path/to/helper".into());

    // List available scanners
    let devices = client.get_devices()?;
    for device in devices {
        println!("Found scanner: {} ({})", device.name, device.id);
    }

    // Scan a document
    if let Some(device) = devices.first() {
        let result = client.scan_to_images(
            &device.id,
            Some(Driver::Apple),
            300,  // DPI
            None, // Default paper source
        )?;

        println!("Scanned {} pages", result.image_paths.len());
    }

    Ok(())
}
