How to idiomatically alias a crate in Rust 2018?
I have a crate foo_sys. In Rust 2015 I used extern crate foo_sys as foo for convenience, but in Rust 2018 extern crate isn't needed anymore and I don't want to use it only for aliasing. When dropping extern crate, I get
error[E0463]: can't find crate for
foo

This can be achieved with the rename-dependency Cargo feature, available in Rust 1.31. With this feature, it's possible to provide a package attribute to the dependencies:
The rename-dependency feature allows you to import a dependency with a different name from the source. This can be useful in a few scenarios:
- Depending on crates with the same name from different registries.
- Depending on multiple versions of a crate.
- Avoid needing
extern crate foo as barin Rust source.
Instead of writing
[dependencies]
foo_sys = "0.2"
the package key can be added to the dependency in Cargo.toml:
[dependencies]
foo = package = "foo_sys", version = "0.2"

But if you don't want to use Cargo.toml renaming for some reason, you can still use the old syntax. It's soft-deprecated, but not removed. So this still works:
extern crate foo_sys as foo;
