A Rust library providing a safe API around native abstractions for Node.
Nanny collaborates with the V8 embedding API to safely monitor stack-allocated handles to garbage-collected objects. This ensures that all objects rooted in the stack are safely tracked by the garbage collector.
A good nanny keeps the nursery safe.
A complete example can be found in the nanny-demo repository. The demo makes use of the rust-bindings npm package to completely automate the process of building and requiring a Rust module in Node.
A JS function is represented in Rust as an extern function that takes a reference to a Call
object. The Call
object allows you to create memory management scopes, which safely manage the rooting of handles to garbage-collected JS values:
```rust
extern fn makeanarray(call: &Call) {
let realm = call.realm(); // current VM execution context
realm.scoped(|scope| { // create a scope for rooting handles
let mut array: Handle
