Changelog

Sourced from histogram's changelog.

[1.4.1] - 2026-05-19

Added

• Midpoint-based mean() on the borrowed CumulativeROHistogramRef / CumulativeROHistogram32Ref views. The mean is stored on the view (computed once at construction, or carried over from the owned histogram's cached value), so mean() is a cheap field access exposed just like count() — no per-call streaming computation — letting a zero-alloc reducer fold it in directly. Returns None for an empty histogram.

Changed

• CumulativeROHistogramRef / CumulativeROHistogram32Ref no longer implement Eq (they now carry an f64 mean); PartialEq is retained.

[1.4.0] - 2026-05-19

Added

• Midpoint-based mean() on CumulativeROHistogram / CumulativeROHistogram32 — the mean of all observations, estimated from bucket midpoints, computed once at construction time across from_parts, From<&Histogram>, and From<&SparseHistogram>. Returns None for an empty histogram.

Changed

• CumulativeROHistogram / CumulativeROHistogram32 no longer implement Eq (they now store an f64 mean); PartialEq is retained. The borrowed *Ref view types are unaffected.

[1.3.1] - 2026-04-29

Added

• CumulativeROHistogramRef<'a> / CumulativeROHistogram32Ref<'a> and SparseHistogramRef<'a> / SparseHistogram32Ref<'a> — borrowed views over histogram storage that mirror the read-only API surface of the owned types. Lets columnar consumers compute quantiles directly off &[u32] slices without per-snapshot allocation or revalidation.
• from_parts_unchecked constructor on each ref type for hot-path use where invariants are already known to hold; from_parts validates as before.
• as_ref() on CumulativeROHistogram* and SparseHistogram* returning the matching ref view; From<&Owned> for OwnedRef<'_> for trait-based conversion.
• SampleQuantiles impl on each ref type.

[1.3.0] - 2026-04-29

Added
