Functions ¶
func ClampFloat64 ¶
ClampFloat64 limits the provided value according to the given range. Origin: https://docs.unity3d.com/ScriptReference/Mathf.Clamp.html.
Types ¶
type Counter ¶
type Counter[T CounterValue] interface { // Inc increments the counter by the given value. Inc(i T) // Dec decrements the counter by the given value. Dec(i T) // Count returns the current value of the counter. Count() T }
Counter is a thread-safe metrics counter.
func NewInt64Counter ¶ added in v0.0.5
NewInt64Counter creates an int64 counter referring to a parent counter. If parent is nil, the root in the hierarchy is created.
type CounterValue ¶ added in v0.0.5
CounterValue is a supported counter numeric type. constraints.Integer is too wide here, we should use the narrowest constraint matching real implementation.
type EMASmoother ¶ added in v0.0.5
type EMASmoother struct {
// contains filtered or unexported fields
}
EMASmoother is a concurrency-safe exponential moving average calculator.
It helps stabilize noisy measurements (for example, memory utilization) so control logic reacts to trend changes instead of short spikes.
func NewEMASmoother ¶ added in v0.0.5
func NewEMASmoother(alpha float64) *EMASmoother
NewEMASmoother creates a new exponential moving average calculator.
The smoothing coefficient alpha is usually in (0; 1]: smaller alpha -> smoother but slower reaction, larger alpha -> faster reaction but noisier output.
func (*EMASmoother) Update ¶ added in v0.0.5
func (e *EMASmoother) Update(value float64) float64
Update adds a new sample and returns the current smoothed value.
Formula:
S_t = alpha*X_t + (1-alpha)*S_{t-1}
