Beschreibung
The following:
fn lifetime<'a>() -> &'a str {
"Why some people do that"
}
Can be more clearly written as this. Also, using 'static lifetime makes it clear that it was intended, especially in unsafe code where returning unbound lifetime may as well be a mistake.
fn lifetime() -> &'static str {
"Why some people do that"
}
