Functions ¶

func DefaultRoundFunc ¶

func DefaultRoundFunc(v float64) int

DefaultRoundFunc is the default function to convert CPU quota from float to int. It rounds the value down (floor).

Types ¶

type CPUQuotaStatus ¶

type CPUQuotaStatus int

CPUQuotaStatus presents the status of how CPU quota is used

const (
	// CPUQuotaUndefined is returned when CPU quota is undefined
	CPUQuotaUndefined CPUQuotaStatus = iota
	// CPUQuotaUsed is returned when a valid CPU quota can be used
	CPUQuotaUsed
	// CPUQuotaMinUsed is returned when CPU quota is smaller than the min value
	CPUQuotaMinUsed
)

func CPUQuotaToGOMAXPROCS ¶

func CPUQuotaToGOMAXPROCS(minValue int, round func(v float64) int) (int, CPUQuotaStatus, error)

CPUQuotaToGOMAXPROCS converts the CPU quota applied to the calling process to a valid GOMAXPROCS value. The quota is converted from float to int using round. If round == nil, DefaultRoundFunc is used.
