Enum envoy_sdk::extension::filter::http::FilterDataStatus

#[repr(u32)]
#[non_exhaustive]pub enum FilterDataStatus {
    Continue,
    StopIterationAndBuffer,
}

Return codes for on_request_body and on_response_body filter invocations.

Envoy bases further filter invocations on the return code of the previous filter.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Continue

Continue filter chain iteration.

If headers have not yet been sent to the next filter, they will be sent first. If data has previously been buffered, the data in this callback will be added to the buffer before the entirety is sent to the next filter.

StopIterationAndBuffer

Do not iterate to any of the remaining filters in the chain, and buffer body data for later dispatching.

To resume filter iteration at a later point, e.g. after enough data has been buffered to make a decision, call resume_request or resume_response respectively.

This should be called by filters which must parse a larger block of the incoming data before continuing processing and so can not push back on streaming data via watermarks.

If buffering the request causes buffered data to exceed the configured buffer limit, a 413 will be sent to the user. On the response path exceeding buffer limits will result in a 500.
