Functions

func DeletePerUserValidationMetrics added in v1.8.0 

func DeletePerUserValidationMetrics(userID string, log log.Logger)

func MaxDurationPerTenant added in v1.7.0 

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 SetDefaultLimitsForYAMLUnmarshalling added in v0.6.0 

func SetDefaultLimitsForYAMLUnmarshalling(defaults Limits)

SetDefaultLimitsForYAMLUnmarshalling sets global default limits, used when loading Limits from YAML files. This is used to ensure per-tenant limits are defaulted to those values.

func SmallestPositiveIntPerTenant added in v1.7.0 

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(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 unlimted so the method will return 0 only if all inputs have a limit of 0 or an empty tenant list is given.
