```{index} single: bucket_ratio; Hash::Util function ``` ```{index} single: Hash::Util::bucket_ratio; Perl function ``` # bucket_ratio Return a `"used/total"` string describing how many of the hash's internal buckets hold at least one key. ## Synopsis my $r = bucket_ratio(%hash); # e.g. "5/8" Behaves like the pre-5.25 `scalar(%hash)`: for a tied hash it calls the `SCALAR` tie method; for a normal empty hash it returns `0`; otherwise it reports the count of non-empty buckets followed by a slash followed by the total bucket count. Useful when eyeballing load factor on a large hash. For a structured report reach for `bucket_stats` or `bucket_stats_formatted` instead.
