We now include the prelude in so many places, this simplifies how we can present how `cargo-test-support` works. Yes, this included some `use` clean ups but its already painful enough walking through every test file, I didn't want to do it twice.

[ADDING] bar v0.1.0 (latest: v0.2.0)
|
|
[WARNING] path override for crate `a` has altered the original list of
|
|
dependencies; the dependency on `bar` was either added or
|
|
modified to not match the previously resolved version
|
|
|
|
This is currently allowed but is known to produce buggy behavior with spurious
|
|
recompiles and changes to the crate graph. Path overrides unfortunately were
|
|
never intended to support this feature, so for now this message is just a
|
|
warning. In the future, however, this message will become a hard error.
|
|
|
|
To change the dependency graph via an override it's recommended to use the
|
|
`[patch]` feature of Cargo instead of the path override feature. This is
|
|
documented online at the url below for more information.
