Overview ¶

Package vec provides label vectors: a metric declared once with label names, then fetched per label-value tuple. Children are cached so the hot path takes no collector lock.

Index ¶

func SetArityHook(f func(name string, want, got int)) (restore func())
type Vec
- func New[T any](name string, labelNames []string, build func(map[string]string) T, sink T) *Vec[T]
- func (v *Vec[T]) With(values ...string) T

Functions ¶

func SetArityHook ¶

func SetArityHook(f func(name string, want, got int)) (restore func())

SetArityHook replaces what happens on a wrong-arity With call and returns a function that restores the previous hook. Tests use it to fail loudly.

Types ¶

type Vec ¶

type Vec[T any] struct {
	// contains filtered or unexported fields
}

Vec is a metric with declared label names.

func New ¶

func New[T any](name string, labelNames []string, build func(map[string]string) T, sink T) *Vec[T]

New declares a vector. build builds the child for one label set; sink is returned on a wrong-arity call.

func (*Vec[T]) With ¶

func (v *Vec[T]) With(values ...string) T

With returns the child for the given label values, in labelNames order.
