Functions

func AbsInt added in v0.7.0

func AbsInt(a int) int

func DurationMinusBuffer added in v0.7.0

func DurationMinusBuffer(intv time.Duration, buffer time.Duration, jitter int64) time.Duration

DurationMinusBuffer returns a duration, minus a buffer and jitter subtracted from the duration. This function is used primarily for servicing Consul TTL Checks in advance of the TTL.

func DurationMinusBufferDomain added in v0.7.0

func DurationMinusBufferDomain(intv time.Duration, buffer time.Duration, jitter int64) (min time.Duration, max time.Duration)

DurationMinusBufferDomain returns the domain of valid durations from a call to DurationMinusBuffer. This function is used to check user specified input values to DurationMinusBuffer.

func EnsurePath added in v0.7.3

func EnsurePath(path string, dir bool) error

EnsurePath is used to make sure a path exists

func MaxInt added in v0.7.0

func MaxInt(a, b int) int

func MinInt added in v0.7.0

func MinInt(a, b int) int

func RandomStagger

func RandomStagger(intv time.Duration) time.Duration

Returns a random stagger interval between 0 and the duration

func RateScaledInterval

func RateScaledInterval(rate float64, min time.Duration, n int) time.Duration

RateScaledInterval is used to choose an interval to perform an action in order to target an aggregate number of actions per second across the whole cluster.

func SeedMathRand

func SeedMathRand()

SeedMathRand provides weak, but guaranteed seeding, which is better than running with Go's default seed of 1. A call to SeedMathRand() is expected to be called via init(), but never a second time.

func StrContains

func StrContains(l []string, s string) bool

StrContains checks if a list contains a string
