ReDevPlugin Worker SDK

redevplugin-worker-sdk is the Rust SDK for backend workers that run inside the sandboxed ReDevPlugin WASM runtime. It owns ABI v2 request decoding, canonical success and error responses, buffer allocation, worker exports, and brokered storage and network hostcalls.

Versioned Dependency

Pin the SDK to the same immutable ReDevPlugin release used by the host:

[dependencies]
redevplugin-worker-sdk = "=0.7.19"
serde_json = "1.0"

Resolve the crate from the same formal registry publication and platform package set as the Host, contracts, IPC, WASM ABI, classifier, and runtime source crates. Do not substitute a Git checkout or local path dependency.

Worker Entry Point

use redevplugin_worker_sdk::{WorkerRequest, WorkerResult, export_worker};
use serde_json::json;

fn handle(request: WorkerRequest) -> WorkerResult {
    match request.method.as_str() {
        "example.greet" => Ok(json!({ "message": "Hello from WASM" })),
        _ => Err(redevplugin_worker_sdk::WorkerError::invalid_request(
            "unsupported method",
        )),
    }
}

export_worker!(handle);

Compile the worker for wasm32-unknown-unknown. The generated module exports the allocator, deallocator, and invocation functions required by redevplugin-wasm-worker-v2.

Hostcalls

• storage::files, storage::kv, and storage::sqlite use Host-minted storage grants for stores declared by the plugin manifest.
• network::execute uses a declared connector and the Host-controlled network broker.
• Workers never receive bearer credentials, raw sockets, ambient filesystem access, or direct network access.

The SDK returns structured WorkerError values. Hostcall failures retain their stable platform code and user-safe message instead of exposing transport or credential details.
