Variables

❖
var ErrLimited = errors.New("rate limit exceeded")

ErrLimited is returned in the request path when the rate limiter is triggered and the request is rejected.

func NewDelayingLimiter Uses

❖
func NewDelayingLimiter(limit Waiter) endpoint.Middleware

NewDelayingLimiter returns an endpoint.Middleware that acts as a request throttler. Requests that would exceed the maximum request rate are delayed via the Waiter function

func NewErroringLimiter Uses

❖
func NewErroringLimiter(limit Allower) endpoint.Middleware

NewErroringLimiter returns an endpoint.Middleware that acts as a rate limiter. Requests that would exceed the maximum request rate are simply rejected with an error.

type Allower Uses

❖
type Allower interface {
    Allow() bool
}

Allower dictates whether or not a request is acceptable to run. The Limiter from "golang.org/x/time/rate" already implements this interface, one is able to use that in NewErroringLimiter without any modifications.

type AllowerFunc Uses

❖
type AllowerFunc func() bool

AllowerFunc is an adapter that lets a function operate as if it implements Allower

func (AllowerFunc) Allow Uses

❖
func (f AllowerFunc) Allow() bool

Allow makes the adapter implement Allower

type Waiter Uses

❖
type Waiter interface {
    Wait(ctx context.Context) error
}

Waiter dictates how long a request must be delayed. The Limiter from "golang.org/x/time/rate" already implements this interface, one is able to use that in NewDelayingLimiter without any modifications.

type WaiterFunc Uses

❖
type WaiterFunc func(ctx context.Context) error

WaiterFunc is an adapter that lets a function operate as if it implements Waiter

func (WaiterFunc) Wait Uses

❖
func (f WaiterFunc) Wait(ctx context.Context) error

Wait makes the adapter implement Waiter
