Types ¶
type Transformation ¶
Transformation defines a function that calculates a time.Duration based on the given duration.
func Deviation ¶
func Deviation(generator *rand.Rand, factor float64) Transformation
Deviation creates a Transformation that transforms a duration into a result duration that deviates from the input randomly by a given factor.
The given generator is what is used to determine the random transformation. If a nil generator is passed, a default one will be provided.

func Equal ¶
func Equal(generator *rand.Rand) Transformation
Equal creates a Transformation that transforms a duration into a result duration in [n/2, n) randomly, where n is the given duration.
The given generator is what is used to determine the random transformation. If a nil generator is passed, a default one will be provided.

func Full ¶
func Full(generator *rand.Rand) Transformation
Full creates a Transformation that transforms a duration into a result duration in [0, n) randomly, where n is the given duration.
The given generator is what is used to determine the random transformation. If a nil generator is passed, a default one will be provided.

func NormalDistribution ¶
func NormalDistribution(generator *rand.Rand, standardDeviation float64) Transformation
NormalDistribution creates a Transformation that transforms a duration into a result duration based on a normal distribution of the input and the given standard deviation.
The given generator is what is used to determine the random transformation. If a nil generator is passed, a default one will be provided.
