clippy::pub_use: using `pub use`

What it meansRestricts the usage of pub use ... It is in the restriction group and off by default.

What you see

warning: using `pub use`

  = help: move the exported item to a public module instead
  = help: for further information visit https://rust-lang.github.io/rust-clippy/stable/index.html#pub_use
  = note: requested on the command line with `-W clippy::pub-use`

Real output of Clippy 0.1.99 (Rust 1.99) on the example below. Names and line numbers in yours will differ.

Does it matter?

A project may wish to limit pub use instances to prevent unintentional exports, or to encourage placing exported items directly in public modules.

Lints that forbid language features for specific codebases (no unwrap, no indexing...). Off by default; pick them one by one, never the whole group.

How to fix it

Clippy does not fix this one automatically. Change the code by hand:

Flagged

pub mod outer {
    mod inner {
        pub struct Test {}
    }
    pub use inner::Test;
}

use outer::Test;

Write this instead

pub mod outer {
    pub struct Test {}
}

use outer::Test;

Turn it off, or on

It is off by default. To use it, set it to warn or deny:

Whole crate (Cargo.toml)

[lints.clippy]
pub_use = "warn"

In code

#![warn(clippy::pub_use)]

One run

cargo clippy -- -W clippy::pub-use

The [lints] table needs Rust 1.74 or newer. In a workspace, put it under [workspace.lints.clippy] and add [lints] workspace = true to each member.

What it does

Restricts the usage of pub use ...

Why restrict this?

A project may wish to limit pub use instances to prevent unintentional exports, or to encourage placing exported items directly in public modules.

Example

pub mod outer {
    mod inner {
        pub struct Test {}
    }
    pub use inner::Test;
}

use outer::Test;

Use instead:

pub mod outer {
    pub struct Test {}
}

use outer::Test;
