Mecha10 Node Resolver

Lightweight runtime resolver for downloading and spawning mecha10 framework nodes. This crate is designed to be embedded in robot binaries to enable runtime download of pre-compiled framework nodes, avoiding slow cross-compilation during build.

Usage

use mecha10_node_resolver::NodeResolver;
use std::collections::HashMap;

# async fn example() -> anyhow::Result<()> {
let resolver = NodeResolver::new()?;

// Check if it's a framework node
if NodeResolver::is_framework_node("@mecha10/speaker") {
    // Resolve (downloads if needed)
    let binary_path = resolver.resolve("speaker").await?;

    // Spawn as subprocess
    let mut env = HashMap::new();
    env.insert("REDIS_URL".to_string(), "redis://localhost:6379".to_string());
    let child = resolver.spawn("speaker", env).await?;
}
# Ok(())
# }
