Under each method, its extensions (Q CS XT Z ZZ IB W U): bold and ticked, it exists; struck, it does not. The extensions and what they mean
Examples: 0 come from the library's tests; 5 were composed from each method's signature and run for this page, on a fresh object, for example o1 = new stzLatencyHistogram(). 7 methods have none yet. Examples run on 2026-10-03 20:23 inside the library at commit 0e72e2e2c.
Method
Explanation, as the source carries it
init
(no comment in the source: the name reads as a sentence) initno extension
Handle
(no comment in the source: the name reads as a sentence) handleno extension
AdoptHandle
Adopt an engine histogram OWNED ELSEWHERE (a perf metric family's child): frees any self-created handle; Destroy() will not free an adopted one -- the owner does.no extension
Record
Tally one latency sample, in milliseconds.no extension
Percentile
Upper bound (ms) of the bucket holding percentile nP (0..100).no extension
P50
Same as Percentile: Upper bound (ms) of the bucket holding percentile nP (0..100).no extension
composed example
o1 = new stzLatencyHistogram() ? o1.P50() #--> 0composed from the signature, run for this page
P95
Same as Percentile: Upper bound (ms) of the bucket holding percentile nP (0..100).no extension
composed example
o1 = new stzLatencyHistogram() ? o1.P95() #--> 0composed from the signature, run for this page
P99
Same as Percentile: Upper bound (ms) of the bucket holding percentile nP (0..100).no extension
composed example
o1 = new stzLatencyHistogram() ? o1.P99() #--> 0composed from the signature, run for this page
Count
(no comment in the source: the name reads as a sentence) countno extension
composed example
o1 = new stzLatencyHistogram() ? o1.Count() #--> 0composed from the signature, run for this page
Sum
Exact running sum of every recorded value (the buckets quantize, the sum does not) -- lifetime mean = Sum()/Count().no extension
composed example
o1 = new stzLatencyHistogram() ? o1.Sum() #--> 0composed from the signature, run for this page
Reset
(no comment in the source: the name reads as a sentence) resetno extension
Destroy
(no comment in the source: the name reads as a sentence) destroyno extension
