I don't think this is right. Imho, Limit=0
should mean "allow 0 requests" ("always block").
What would you think of
httprate.WithNoLimit()
(akaLimit=-1
)- or zero increment
httprate.WithIncrement(0)
instead?

I do it in the only place where this is used: https://github.com/klaidliadon/httprate/blob/ac748ea5a6b8921aef7a442985c77657a989932f/limiter.go#L90-L97
increment, ok := getIncrement(r.Context())
if !ok {
increment = 1
}
// If the increment is 0, we do not limit
if increment == 0 {
return false
}
} | ||
// If the limit is set to 0, we are always over limit | ||
if limit == 0 { | ||
return true |
