How to disable the warning "unused import" instead of using #[allow(unused)] all the time?

1

Hi there!
well, i had a problem of the warning about unused crates/imports or even variables, i want to disable all of them, since i'm just learning, and sometimes i don't need to use them at that time, nd i don't wanna delete them, so, how can i avoid that warning?
thank you all ^^

Delete the import? :slight_smile:

one trick is use #![allow(unused)] at the top of the file. Notice the exclamation point. This will disable the warning for the entire file instead of having to add the attribute for every usage.

Doing that will disable it for the entire module, as well as all its submodules.

Lints (that is, warnings) can now (finally) be configured project-wide in Cargo.toml. Just add this to your Cargo.toml:

[lints.rust]
unused_imports = "allow"

Another way is to add the following to your Cargo config:

[build]
rustflags = "-Aunused_imports"

which makes cargo to always pass the above parameter to the compiler, [A]llowing the lint.
