Using rlibs in rust

hey I've been trying to compile an rlib into my project.

cargo.toml
[dependencies]

rlibtest = {"path"="../liblibtest"}

but i get this

dependencies expects a Cargo package, which it will build as part of the larger build.
An rlib is the final product of a compilation step. Cargo passes them around under the hood to rustc.

So the question is: what are you really trying to do there? What does your project look like and why do you think using an rlib directly is the way to go?

You can't use rlib with Cargo. Rust doesn't have a stable ABI, so you pretty much can't use them at all. Threat them as an internal implementation detail of Rust that is not for users.

well I'm making a game engine and i wanted to use a static library to share it across projects compared to having cargo install it as a dependency every single time. And in the built version I wanted to compile the library into the binary.
