Function cargo::core::compiler::links::validate_links

pub fn validate_links(
    resolve: &Resolve,
    unit_graph: &UnitGraph,
) -> CargoResult<()>

Validates package.links field in the manifest file does not conflict between packages.

NOTE: This is the old links validator. Links are usually validated in the resolver. However, the links field was added to the index in early 2018 (see rust-lang/cargo#4978). However, links has been around since 2014, so there are still many crates in the index that don’t have links properly set in the index (over 600 at the time of this writing in 2019). This can probably be removed at some point in the future, though it might be worth considering fixing the index.
