pub fn nearest<'a>(
typed: &str,
names: impl Iterator<Item = &'a str>,
) -> Option<&'a str>Expand description
The closest command name to typed, when one is close enough to be
worth suggesting.
The threshold is deliberately tight. A suggestion that is wrong is
worse than none: the reader types it, gets a second refusal, and now
distrusts the first one. One third of the typed length, so revieww
suggests review and deploy suggests nothing at all.
