Types

type Config

type Config struct {
	Label  string `json:"label" yaml:"label"`
	Type   string `json:"type" yaml:"type"`
	Plugin any    `json:"plugin,omitempty" yaml:"plugin,omitempty"`
}

Config is the all encompassing configuration struct for all cache types. Deprecated: Do not add new components here. Instead, use the public plugin APIs. Examples can be found in: ./internal/impl.

func NewConfig

func NewConfig() Config

NewConfig returns a configuration struct fully populated with default values. Deprecated: Do not add new components here. Instead, use the public plugin APIs. Examples can be found in: ./internal/impl.

func (*Config) UnmarshalYAML

func (conf *Config) UnmarshalYAML(value *yaml.Node) error

UnmarshalYAML ensures that when parsing configs that are in a map or slice the default values are still applied.

type V1

type V1 interface {
	// Access the rate limited resource. Returns a duration or an error if the
	// rate limit check fails. The returned duration is either zero (meaning the
	// resource may be accessed) or a reasonable length of time to wait before
	// requesting again.
	Access(ctx context.Context) (time.Duration, error)

	// Close the component, blocks until either the underlying resources are
	// cleaned up or the context is cancelled. Returns an error if the context
	// is cancelled.
	Close(ctx context.Context) error
}

V1 is a common interface implemented by rate limits.

func MetricsForRateLimit

func MetricsForRateLimit(r V1, stats metrics.Type) V1

MetricsForRateLimit wraps a ratelimit.V2 with a struct that implements types.RateLimit.
