Crate fs_core 

In-memory filesystem implementation shared by every Monaka component.

A single Fs type is exposed in two flavours via the thread-safe feature flag:

• thread-safe (requires std): backed by DashMap plus Arc<RwLock<Inode>>, used by host-side wasmtime integrations that need Send + Sync.
• default: backed by RefCell<HashMap> or RefCell<BTreeMap> plus Rc<RefCell<Inode>>, used by the WASI components.

Both flavours share one &self API, so consumers only need to pick the feature flag that matches their target.
