Issue Description

When using the RateLimiter Middleware with a rate between 0 and 1 all events will be rejected instead of applying the specified rate. E.g.: e.Use(middleware.RateLimiter(middleware.NewRateLimiterMemoryStore(0.5)))

I am not saying that it is a common use case to have

Let's support at least reading "b3" header from a single string, most commonly traceid-spanid-1
It would also be nice to support optionally writing this, especially in message providers or others with constrained environments.

Expected behavior

As discussed on openzipkin/b3-propagation#21 and first implemented here: https://github.com/openzipkin/brave/blob/master/brave/src/main/java/bra

服务

Currently, we proivde FilteredHttpRequest and FilteredHttpResponse for tranforming a headers or data.
But it is a bit difficult to implement FilteredHttp* because users have to check the type of HttpObject.
Most users might not know the hierarchical relation between HttpOject, HttpHeaders, ResponseHeaders and HttpData

return new FilteredHttpResponse(response) {
      

Currently we have a mix of:

• Out of memory error.
• Out of memory error
• out of memory error
• out of memory
• out of memory.
• out of memory [some context]

All these should be adjusted to use the same wording for consistency and it should also make the executable a little bit smaller 😄
