== Why is this an issue?
|
|
|
|
When defining arrays in Rust, it is possible to forget a comma between elements, especially when the elements are binary operator expressions that span multiple lines. This can lead to unexpected results, causing logical errors or runtime issues.
|
|
|
|
The origin of this problem is often due to oversight or formatting changes that split expressions across lines without adding the necessary comma.
|
|
|
|
== How to fix it
|
|
|
|
To fix this issue, add commas after each element or write the entire array on a single line.

==== Noncompliant code example
|
|
|
|
[source,rust,diff-id=1,diff-type=noncompliant]
|
|
----
|
|
let a = &[
|
|
-1, -2, -3 // Noncompliant: <= no comma here
|
|
-4, -5, -6
|
|
];
|
|
----
|
|
|
|
==== Compliant solution
|
|
|
|
[source,rust,diff-id=1,diff-type=compliant]
|
|
----
|
|
let a = &[
|
|
-1, -2, -3,
|
|
-4, -5, -6,
|
|
];
