clippy::doc_broken_link: possible broken doc link: broken across multiple lines

What it meansChecks the doc comments have unbroken links, mostly caused by bad formatted links such as broken across multiple lines. It is in the pedantic group and off by default.

What you see

  = note: `-W clippy::doc-broken-link` implied by `-W clippy::pedantic`

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?

Because documentation generated by rustdoc will be broken since expected links won’t be links and just text.

Stricter lints with some false positives. Off by default; opt in with clippy::pedantic.

How to fix it

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

Flagged

/// [example of a bad link](https://
/// github.com/rust-lang/rust-clippy/)
pub fn do_something() {}

Write this instead

/// [example of a good link](https://github.com/rust-lang/rust-clippy/)
pub fn do_something() {}

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]
doc_broken_link = "warn"

In code

#![warn(clippy::doc_broken_link)]

One run

cargo clippy -- -W clippy::doc-broken-link

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.

Clippy's own documentation

What it does

Checks the doc comments have unbroken links, mostly caused by bad formatted links such as broken across multiple lines.

Why is this bad?

Because documentation generated by rustdoc will be broken since expected links won’t be links and just text.

Examples

This link is broken:

/// [example of a bad link](https://
/// github.com/rust-lang/rust-clippy/)
pub fn do_something() {}

It shouldn’t be broken across multiple lines to work:

/// [example of a good link](https://github.com/rust-lang/rust-clippy/)
pub fn do_something() {}

From the Clippy lint list (0.1.99), part of the Rust project, MIT or Apache-2.0. Official entry.
