UnitTypes holds the definition of units known to pprof.
Functions ¶
func CommonValueType ¶
CommonValueType returns the finest type from a set of compatible types.
func Percentage ¶
Percentage computes the percentage of total of a value, and encodes it as a string. At least two digits of precision are printed.
func Scale ¶
Scale a measurement from a unit to a different unit and returns the scaled value and the target unit. The returned target unit will be empty if uninteresting (could be skipped).
func ScaleProfiles ¶
ScaleProfiles updates the units in a set of profiles to make them compatible. It scales the profiles to the smallest unit to preserve data.
func ScaledLabel ¶
ScaledLabel scales the passed-in measurement (if necessary) and returns the label used to describe a float measurement.
