prefer_early_return

A rule which highlights if statements that span the entire body, and suggests replacing them with a reversed boolean check with an early return.

Example

BAD:

void func() {
  if (a) { //LINT
    if (b) { //LINT
      c;
    }
  }
}

GOOD:

void func() {
  if (!a) return;
  if (!b) return;
  c;
}
