QUESTION
There's a crate I want to use as a library for some of my own code (speedtest-rs specifically, but it doesn't really matter). However, whenever I try to use this crate, the compiler doesn't want to play nice with it.
...ANSWER
Answered 2020-Jul-26 at 18:22Some googling has shown me that binary crates just have an extra link step, so I should be able to link against them, right?
No. It's not that simple. Plus that extra step creates an executable file rather than a library file. An executable cannot be used as a library.
I know a lot of Rust packages have both a library and a binary in them, but what do you do when an author does not seem to follow this pattern?
You can:
- Ask them on GitHub to publish a library.
- Fork the crate and make your own library (which you can do since it is published with the usual dual “Apache License, Version 2.0” + “MIT” license).
There isn't an automated way to use a binary crate as a library because in particular:
- Rust won't generate a library.
- Since the crate is missing a
src/lib.rs
file, nothing is exported. This is akin to have all items in that crate private. You wouldn't be able to use anything.
