Module stats 

Structs

IsConstant

IsSorted

IsStrictSorted

LowerBound

Interpret the value as a lower bound. These form a partial order over successively more precise bounds

Max

These structs allow the extraction of the bound from the Precision value. They tie together the Stat and the StatBound, which allows the bound to be extracted.

Min

NaNCount

NullCount

Sum

UncompressedSizeInBytes

UpperBound

Interpret the value as an upper bound, see LowerBound for more details.

Enums

IntersectionResult

The result of the fallible intersection of two bound, defined to avoid Option IntersectionResult mixup.

Precision

A statistic has a precision Exact or Inexact. This represents uncertainty in that value. Exact values are computed, where can inexact values are likely inferred from compute functions.

Stat

Traits

StatBound

StatBound defines the operations that can be performed on a bound. The main bounds are Upper (e.g. max) and Lower (e.g. min).

StatType

StatType define the bound of a given statistic. (e.g. Max is an upper bound), this is used to extract the bound from a Precision value, (e.g. p::bound<Max>()).
