Function targets 

pub fn targets(
    resolve: &Resolve,
    world: WorldId,
    component_to_test: &[u8],
    semver_compatible: bool,
) -> Result<()>

This function checks whether component_to_test correctly conforms to the world specified. It does so by instantiating a generated component that imports a component instance with the component type as described by the “target” world.

When semver_compatible is set, interfaces are matched by their canonical names, so semver-compatible versions (e.g. wasi:cli@0.2.3 and wasi:cli@0.2.0) are matched with each other and then type-checked structurally.
