Crate spin_core

Spin core execution engine

This crate provides low-level Wasm functionality required by Spin. Most of this functionality consists of wrappers around wasmtime that narrow the flexibility of wasmtime to the set of features used by Spin (such as only supporting wasmtime’s async calling style).

Re-exports

• pub use wasmtime;
