Cargo Features

wasm3-sys has no features set by default.

[dependencies]
wasm3-sys = { version = "0.3.0", features = ["wasi", "use-32bit-slots", "build-bindgen"] }
wasi
use-32bit-slots
build-bindgen = bindgen

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
