* Remove usage of `CompilationStrategy` from `Config` This commit removes the public API usage of the internal `CompilationStrategy` enumeration from the `Config` type in the `wasmtime` crate. To do this the `enum` was copied locally into the crate and renamed `Strategy`. The high-level description of this change is: * The `Config::strategy` method now takes a locally-defined `Strategy` enumeration instead of an internal type. * The contents of `Strategy` are always the same, not relying on Cargo features to indicate which variants are present. This avoids unnecessary downstream `#[cfg]`. * A `lightbeam` feature was added to the `wasmtime` crate itself to lightbeam compilation support. * The `Config::strategy` method is now fallible. It returns a runtime error if support for the selected strategy wasn't compiled in. * The `Strategy` enum is listed as `#[non_exhaustive]` so we can safely add variants over time to it. This reduces the public crate dependencies of the `wasmtime` crate itself, removing the need to reach into internal crates even more! cc #708 * Fix fuzz targets * Update nightly used to build releases * Run rustfmt
This is the wasmtime-environ crate, which contains the implementations
of the ModuleEnvironment and FuncEnvironment traits from
cranelift-wasm. They effectively
implement an ABI for basic wasm compilation that defines how linear memories
are allocated, how indirect calls work, and other details. They can be used
for JITing, native object files, or other purposes.
