These default features are set whenever wasmer-c-api is added without default-features = false somewhere in the dependency tree.

WARNING!

These features are here but, for now (wasmer 6.0.0-alpha1) they do nothing.
In the next alpha release they will be wired up to use the matching backend.
These features are being added now to make CI easier, since we will nonetheless have to add them later.

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.
