Enum rotor_http::client::RecvMode

pub enum RecvMode {
    Buffered(usize),
    Progressive(usize),
}

This type is returned from headers_received handler of either client client or server protocol handler

The marker is used to denote whether you want to have the whole request buffered for you or read chunk by chunk.

The Progressive (chunk by chunk) mode is mostly useful for proxy servers. Or it may be useful if your handler is able to parse data without holding everything in the memory.

Otherwise, it's best to use Buffered mode (for example, comparing with using your own buffering). We do our best to optimize it for you.

Variants

Buffered(usize)

Download whole message body (request or response) into the memory.

The argument is maximum size of the body. The Buffered variant works equally well for Chunked encoding and for read-util-end-of-stream mode of HTTP/1.0, so sometimes you can't know the size of the request in advance. Note this is just an upper limit it's neither buffer size nor minimum size of the body.

Note the buffer size is asserted on if it's bigger than max buffer size

Progressive(usize)

Fetch data chunk-by-chunk.

The parameter denotes minimum number of bytes that may be passed to the protocol handler. This is for performance tuning (i.e. less wake-ups of protocol parser). But it's not an input buffer size. The use of Progressive(1) is perfectly okay (for example if you use http request body as a persistent connection for sending multiple messages on-demand)
