Functions

func IntersectionPerTenant

func IntersectionPerTenant(tenantIDs []string, f func(string) []string) []string

IntersectionPerTenant is returning the intersection of feature flags. This is useful to determine the minimal feature set supported.

func MaxDurationOrZeroPerTenant

func MaxDurationOrZeroPerTenant(tenantIDs []string, f func(string) time.Duration) time.Duration

MaxDurationOrZeroPerTenant is returning the maximum duration per tenant or zero if one tenant has time.Duration(0).

func MaxDurationPerTenant

func MaxDurationPerTenant(tenantIDs []string, f func(string) time.Duration) time.Duration

MaxDurationPerTenant is returning the maximum duration per tenant. Without tenants given it will return a time.Duration(0).

func SmallestPositiveIntPerTenant

func SmallestPositiveIntPerTenant(tenantIDs []string, f func(string) int) int

SmallestPositiveIntPerTenant is returning the minimal positive value of the supplied limit function for all given tenants.

func SmallestPositiveNonZeroDurationPerTenant

func SmallestPositiveNonZeroDurationPerTenant(tenantIDs []string, f func(string) time.Duration) time.Duration

SmallestPositiveNonZeroDurationPerTenant is returning the minimal positive and non-zero value of the supplied limit function for all given tenants. In many limits a value of 0 means unlimited so the method will return 0 only if all inputs have a limit of 0 or an empty tenant list is given.

func SmallestPositiveNonZeroIntPerTenant

func SmallestPositiveNonZeroIntPerTenant(tenantIDs []string, f func(string) int) int

SmallestPositiveNonZeroIntPerTenant is returning the minimal positive and non-zero value of the supplied limit function for all given tenants. In many limits a value of 0 means unlimited so the method will return 0 only if all inputs have a limit of 0 or an empty tenant list is given.
