Struct PacketMetadata 

pub struct PacketMetadata {
    pub direction: Direction,
    pub size: u16,
    pub iat_ms: f64,
    pub entropy: f32,
    pub header_prefix: Vec<u8>,
    pub timestamp_ns: u64,
}

Metadata extracted from a single packet (no payload — privacy-safe)

Fields

direction: Direction

Packet direction (uplink or downlink)

size: u16

Total packet size in bytes

iat_ms: f64

Inter-arrival time from previous packet in milliseconds

entropy: f32

Shannon entropy of packet payload (0.0–8.0)

header_prefix: Vec<u8>

First 16 bytes of the mask-dependent header

timestamp_ns: u64

Monotonic timestamp in nanoseconds
