* Remove the need for `HostRef<Store>` This commit goes through the public API of the `wasmtime` crate and removes the need for `HostRef<Store>`, as discussed in #708. This commit is accompanied with a few changes: * The `Store` type now also implements `Default`, creating a new `Engine` with default settings and returning that. * The `Store` type now implements `Clone`, and is documented as being a "cheap clone" aka being reference counted. As before there is no supported way to create a deep clone of a `Store`. * All APIs take/return `&Store` or `Store` instead of `HostRef<Store>`, and `HostRef<T>` is left as purely a detail of the C API. * The `global_exports` function is tagged as `#[doc(hidden)]` for now while we await its removal. * The `Store` type is not yet `Send` nor `Sync` due to the usage of `global_exports`, but it is intended to become so eventually. * Touch up comments on some examples * Run rustfmt
This is the wasmtime-wasi crate, which implements the
WebAssembly System Interface (WASI) API in Rust.
WASI is greatly inspired by and directly derived from CloudABI. It differs in that it has aspirations to expand to a greater scope, and to better support the needs of WebAssembly engines.
