pub const BUFFERED_REQUEST_LIMIT: u64 = _; // 33_554_432u64Expand description
Most bytes a caller collects in memory for one request body, matching
crate::BUFFERED_READ_LIMIT for response bodies. A single request
carries its whole body, so no object goes in one request past this, even
on a provider accepting more: a large object goes one part at a time and
never has to fit in memory (§17.1).
