I think that the "expression-style" return looks good for short and "expression-like" function. Good fn inc(a: u32) -> u32 { a + 1 }
fn foo(a: u32, b: u32) -> u32 { let x = a + b; a * x }
Bad fn bar(...) -> bool {
let mut success = false;
let conn = getConnection();
...
if x > y {
return false;
} else if z < q {
success = false;
}
foo.barify(x, y);
...
success
}
It looks especially bad when the function has multiple early returns, and then the final return looks different. |
