Enum CollectorMode 

pub enum CollectorMode {
    Sniffer(WifiSnifferConfig),
    Station(WifiStationConfig),
    AccessPoint(WifiApConfig),
}

How a collector obtains the frames it measures.

These are capture paths, not roles: each one ends with this node holding CSI. Which one to use depends on what traffic is available to measure.

Variants

Sniffer(WifiSnifferConfig)

Lock a channel in promiscuous mode and measure every frame overheard.

This is the capture path that pairs with an NodeRole::Emitter: the emitter injects unassociated frames and the sniffer measures them, with no association or handshake between the two.

Station(WifiStationConfig)

Associate as a Wi-Fi station and measure CSI from received frames.

AccessPoint(WifiApConfig)

Run a self-contained softAP: start an access point (plus a minimal DHCP server) so a CollectorMode::Station node can associate and generate steady uplink traffic, measured as CSI here.
