* Reactor support. This implements the new WASI ABI described here: https://github.com/WebAssembly/WASI/blob/master/design/application-abi.md It adds APIs to `Instance` and `Linker` with support for running WASI programs, and also simplifies the process of instantiating WASI API modules. This currently only includes Rust API support. * Add comments and fix a typo in a comment. * Fix a rustdoc warning. * Tidy an unneeded `mut`. * Factor out instance initialization with `NewInstance`. This also separates instantiation from initialization in a manner similar to https://github.com/bytecodealliance/lucet/pull/506. * Update fuzzing oracles for the API changes. * Remove `wasi_linker` and clarify that Commands/Reactors aren't connected to WASI. * Move Command/Reactor semantics into the Linker. * C API support. * Fix fuzzer build. * Update usage syntax from "::" to "=". * Remove `NewInstance` and `start()`. * Elaborate on Commands and Reactors and add a spec link. * Add more comments. * Fix wat syntax. * Fix wat. * Use the `Debug` formatter to format an anyhow::Error. * Fix wat.
This is the wasmtime-runtime crate, which contains wasm runtime library
support, supporting the wasm ABI used by wasmtime-environ,
wasmtime-jit, and wasmtime-obj.
This crate does not make a host vs. target distinction; it is meant to be compiled for the target.
Most users will want to use the main wasmtime crate instead of using this
crate directly.
