This repo shows the effects of non-purely numeric version numbers in a rust workspace:

• Two crates lib-foo and lib-bar.
• lib-foo depends on lib-bar
• lib-bar is at version 0.1.0-dev.0
• lib-foo still declares its dependency on lib-bar at version 0.1.0.

The result is a workspace that can not function: cargo errors out with:

error: no matching package named `lib-bar` found
location searched: /Users/asf/Mess/current/cargo-release-test/lib-bar
prerelease package needs to be specified explicitly
lib-bar = { version = "0.1.0-dev.0" }
required by package `lib-foo v0.1.0 (/Users/asf/Mess/current/cargo-release-test/lib-foo)`
