RS.CLIPPY.UNIT_ARG
Passing unit to a function
This checker is a Clippy lint created by The Rust Project Contributors. The documentation shown here is a copy of the original documentation for: unit_arg. Copyright ©2025 The Rust Team. All rights reserved.
What it does
Checks for passing a unit value as an argument to a function without using a
unit literal (()).
Why is this bad?
This is likely the result of an accidental semicolon.
Example
foo({
let a = bar();
baz(a);
})
