Rates map[string]RateLimitRequest // key = rate name
}

type Unit ¶
type Unit string
Unit enumerates allowed values for the unit a resource's quota/usage is measured in.
const ( //UnitNone is used for countable (rather than measurable) resources. UnitNone Unit = "" //UnitBytes is exactly that. UnitBytes Unit = "B" //UnitKibibytes is exactly that. UnitKibibytes Unit = "KiB" //UnitMebibytes is exactly that. UnitMebibytes Unit = "MiB" //UnitGibibytes is exactly that. UnitGibibytes Unit = "GiB" //UnitTebibytes is exactly that. UnitTebibytes Unit = "TiB" //UnitPebibytes is exactly that. UnitPebibytes Unit = "PiB" //UnitExbibytes is exactly that. UnitExbibytes Unit = "EiB" //UnitUnspecified is used as a placeholder when the unit is not known. UnitUnspecified Unit = "UNSPECIFIED" )
func (Unit) Base ¶
Base returns the base unit of this unit. For units defined as a multiple of another unit, that unit is the base unit. Otherwise, the same unit and a multiple of 1 is returned.
func (Unit) Parse ¶

UnitMebibytes.Parse("10") -> returns syntax error (missing unit)
UnitNone.Parse("42") -> 42
UnitNone.Parse("42 MiB") -> returns syntax error (unexpected unit)
func (*Unit) UnmarshalYAML ¶
UnmarshalYAML implements the yaml.Unmarshaler interface. This method validates that units in the config file actually exist.
type ValueWithUnit ¶
type ValueWithUnit struct {
Value uint64 `json:"value" yaml:"value"`

}
ValueWithUnit is used to represent values with units in subresources.
func (ValueWithUnit) ConvertTo ¶
func (v ValueWithUnit) ConvertTo(u Unit) (ValueWithUnit, error)
ConvertTo returns an equal value in the given Unit. IncompatibleUnitsError is returned if the source unit cannot be converted into the target unit. FractionalValueError is returned if the conversion does not yield an integer value in the new unit.
func (ValueWithUnit) String ¶
func (v ValueWithUnit) String() string
String appends the unit (if any) to the given value. This should only be used for error messages; actual UIs should be more clever about formatting values (e.g. ValueWithUnit{1048576,UnitMebibytes}.String() returns "1048576 MiB" where "1 TiB" would be more appropriate).
type Window ¶
type Window uint64
Window is the size (in nanoseconds) of the time window that is considered when enforcing a rate limit. For example, a rate limit of "10 per second" has a limit of 10 and a window of 1 second.
This type is very similar to time.Duration, but does not allow negative values and uses a different parsing logic that does not allow phrases with multiple units like time.Duration does (e.g. "2h30m").
const ( //WindowMilliseconds is a Window unit. WindowMilliseconds Window = 1000 * 1000 //WindowSeconds is a Window unit. WindowSeconds Window = 1000 * WindowMilliseconds //WindowMinutes is a Window unit. WindowMinutes Window = 60 * WindowSeconds //WindowHours is a Window unit. WindowHours Window = 60 * WindowMinutes )
func MustParseWindow ¶
MustParseWindow is like ParseWindow, but panics on error. This should only be used for compile-time constants.
func ParseWindow ¶
ParseWindow parses a string representation like "1s" or "5m".
func (Window) MarshalJSON ¶
MarshalJSON implements the json.Marshaler interface.
func (*Window) UnmarshalJSON ¶
UnmarshalJSON implements the json.Unmarshaler interface.
func (*Window) UnmarshalYAML ¶
UnmarshalYAML implements the yaml.Unmarshaler interface. This method validates that windows in the config file are valid.
