Functions

func BodyBuffer 

func BodyBuffer(res *http.Response) ([]byte, error)

func EvaluateAtModifierFunction added in v0.30.0 

func EvaluateAtModifierFunction(query string, start, end int64) (string, error)

EvaluateAtModifierFunction parse the query and evaluates the `start()` and `end()` at modifier functions into actual constant timestamps. For example given the start of the query is 10.00, `http_requests_total[1h] @ start()` query will be replaced with `http_requests_total[1h] @ 10.00` If the modifier is already a constant, it will be returned as is.

func NewRoundTripper 

func NewRoundTripper(next http.RoundTripper, codec Codec, headers []string, middlewares ...Middleware) http.RoundTripper

NewRoundTripper merges a set of middlewares into an handler, then inject it into the `next` roundtripper using the codec to translate requests and responses.
