# gc/census Diagnostic: walk the live heap object list (without collecting) and report per-kind counts, total string bytes, and the 12 largest live strings with snippets. Run after `[gc/collect]` to see what is still reachable when `:live-bytes` will not come down. ## Syntax

[gc/census]

## Examples

[gc/collect]
[gc/census]
# → %{ :live-objects 10461
#      :string-count 6762
#      :string-bytes 255635
#      :kinds %{ :map 1497 :string 6762 :vector 831 :keyword 80 … }
#      :top-strings @{ %{ :len 22662 :snippet "# Two-column" } … } }

## Returns A map with `:live-objects`, `:string-count`, `:string-bytes`, `:kinds` (a map of object-kind keyword → count, non-zero kinds only), and `:top-strings` (up to 12 `%{ :len N :snippet "…" }` maps, snippets capped at 60 chars). Collection is suppressed while the walk runs; `nil` without a VM context. ## See Also `gc/collect`, `gc/stats`, `gc/pools`
