Alex Crichton 7b311004b5 Leverage Cargo's workspace inheritance feature (#4905 )

* Leverage Cargo's workspace inheritance feature

This commit is an attempt to reduce the complexity of the Cargo
manifests in this repository with Cargo's workspace-inheritance feature
becoming stable in Rust 1.64.0. This feature allows specifying fields in
the root workspace `Cargo.toml` which are then reused throughout the
workspace. For example this PR shares definitions such as:

* All of the Wasmtime-family of crates now use `version.workspace =
  true` to have a single location which defines the version number.
* All crates use `edition.workspace = true` to have one default edition
  for the entire workspace.
* Common dependencies are listed in `[workspace.dependencies]` to avoid
  typing the same version number in a lot of different places (e.g. the
  `wasmparser = "0.89.0"` is now in just one spot.

Currently the workspace-inheritance feature doesn't allow having two
different versions to inherit, so all of the Cranelift-family of crates
still manually specify their version. The inter-crate dependencies,
however, are shared amongst the root workspace.

This feature can be seen as a method of "preprocessing" of sorts for
Cargo manifests. This will help us develop Wasmtime but shouldn't have
any actual impact on the published artifacts -- everything's dependency
lists are still the same.

* Fix wasi-crypto tests

wasmtime-wasi-nn

This crate enables support for the wasi-nn API in Wasmtime. Currently it contains an implementation of wasi-nn using OpenVINO™ but in the future it could support multiple machine learning backends. Since the wasi-nn API is expected to be an optional feature of WASI, this crate is currently separate from the wasi-common crate. This crate is experimental and its API, functionality, and location could quickly change.

Use

Use the Wasmtime APIs to instantiate a Wasm module and link in the WasiNn implementation as follows:

let wasi_nn = WasiNn::new(&store, WasiNnCtx::new()?);
wasi_nn.add_to_linker(&mut linker)?;

Build

This crate should build as usual (i.e. cargo build) but note that using an existing installation of OpenVINO™, rather than building from source, will drastically improve the build times. See the openvino crate for more information

Example

An end-to-end example demonstrating ML classification is included in examples:

tests/wasi-nn-rust-bindings contains ergonomic bindings for writing Rust code against the wasi-nn APIs
tests/classification-example contains a standalone Rust project that uses the wasi-nn APIs and is compiled to the wasm32-wasi target using the wasi-nn-rust-bindings

Run the example from the Wasmtime project directory:

ci/run-wasi-nn-example.sh
