The unit type () is always equal to itself and using it in comparisons is either redundant or a mistake, often caused by accidental
semicolon placement.
Code examples
Noncompliant code example
fn foo() {}
fn bar() {}
fn baz() {}
if {
foo();
} == {
bar();
} {
baz();
} // Noncompliant: Comparing unit values.
Compliant solution
fn foo() {}
fn bar() {}
fn baz() {}
foo();
bar();
baz(); // Compliant: No unit comparison.
