Must be empty
This attribute checks that a given function is empty. It is just that.
This can be useful for debugging, when you're just using using cargo test
and want to assure that nobody in a repository puts content in the main function, for example.
Example
use must_be_empty::must_be_empty;
#[must_be_empty]
fn main() {}
If you were to put something in that main
function, it would give a warning or an error, depending on your configuration.
Installation
Put this in your Cargo.toml
file:
[dependencies]
must_be_empty = "0.1.0"
