In rust sdk, those header/body callbacks can only return "Pause" or "Continue" action: ``` pub enum Action { Continue = 0, Pause = 1, } ``` In cpp sdk, there are more: ``` enum class FilterHeadersStatus : int32_t { Continue = 0, StopIteration = 1, ContinueAndEndStream = 2, StopAllIterationAndBuffer = 3, StopAllIterationAndWatermark = 4, }; enum class FilterDataStatus : int32_t { Continue = 0, StopIterationAndBuffer = 1, StopIterationAndWatermark = 2, StopIterationNoBuffer = 3 }; ``` Any plan to bring those additional actions to rust sdk? We hope to have better control over the buffering behavior in our rust filter.
