Function lower_dar_selecting 

pub fn lower_dar_selecting(
    dar: &Dar,
    selection: &Selection,
    external: &ExternalPackages,
) -> Result<(Crate, Vec<SkippedType>), DecodeError>

The same, emitting only the packages a Selection names.

A DAR is generated whole because that is what a DAR describes. Some packages have no DAR of their own, though — daml-stdlib and daml-prim arrive only as somebody else’s dependency — and publishing those as a crate means choosing a subset of a DAR that happens to contain them.

A reference out of the selection that is not covered by external is reported as a skipped type rather than emitted, because the path would name a module this crate does not have.

Errors

As lower_dar.
