Shared libraries

Cargo itself will let you use multiple different versions of the same library in one program, without errors.

You can, however, use cargo-deny, which will tell you about multiple versions in use.

The issue, however, remains developer time. We all agree that using undermaintained versions of code is bad, but nobody is putting in the time to make sure that we're all on maintained versions. And the only difference in that regard between the C ecosystem and the Rust ecosystem is that in the Rust ecosystem, the use of large numbers of small dependencies means that it's easy to spot, where in the C ecosystem, spotting which parts of a big library (like glib) are undermaintained, and which ones are cared for is hidden behind the fact that glib overall is cared for.
