Struct StaticRwndConfig 

pub struct StaticRwndConfig {
    pub duration: Option<Duration>,
    pub set_rcv_buf: Option<u64>,
    pub app_read_bytes: Option<u64>,
}

The configuration struct for StaticRwnd.

The serialized JSON form is flat: a step looks like {"duration":"1s","set_rcv_buf":65536} or {"duration":"1s","app_read_bytes":1024}, and may carry both keys.

The two fields are independent – there is no invariant to enforce, so Serialize/Deserialize are derived. A step with neither field is valid and carries the previous configuration forward.

Unknown keys are rejected rather than ignored. The schema dropped rwnd_remaining, and serde’s default of skipping what it does not recognise would turn a trace written against the old schema into a run of steps that state nothing – a replay that looks healthy while reproducing no receiver at all. Failing to deserialize names the offending field instead.

Fields

duration: Option<Duration>

set_rcv_buf: Option<u64>

app_read_bytes: Option<u64>

Implementations

impl StaticRwndConfig

pub fn new() -> Self

pub fn duration(self, duration: Duration) -> Self

pub fn set_rcv_buf(self, set_rcv_buf: u64) -> Self

Size the receive buffer.

On its own this also holds the advertised window at that value, with the application draining continuously. Combined with Self::app_read it only sets the size: the resize applies first, the read is taken against the new size, and the window then follows set_rcv_buf - unread rather than being pinned.

pub fn app_read(self, bytes: u64) -> Self

The application reads exactly this many bytes over the step, then stops.

The window follows from what is left unread of the standing buffer, or of the buffer this step sets when combined with Self::set_rcv_buf. The backlog carries across such a resize untouched, so the window saturates at zero if the new size is at or below it.
