Struct HeaderDigest 

pub struct HeaderDigest {
    pub frame_control: u16,
    pub addr1: [u8; 6],
    pub addr2: [u8; 6],
    pub addr3: [u8; 6],
    pub seq_ctrl: u16,
}

The fixed part of the measured MPDU’s MAC header: enough to drop retries, tell uplink from downlink and attribute the frame to a transmitter.

Fields

frame_control: u16

Frame control field.

addr1: [u8; 6]

Receiver address.

addr2: [u8; 6]

Transmitter address.

addr3: [u8; 6]

Third address (BSSID, or source/destination depending on To/From DS).

seq_ctrl: u16

Sequence control field.

Implementations

impl HeaderDigest

pub const HEADER_LEN: usize = 24

Length of the header prefix the digest is read from: FC, duration, three addresses and sequence control.

pub fn parse(hdr: &[u8]) -> Option<Self>

Parse the first Self::HEADER_LEN bytes of an 802.11 MAC header. None if hdr is shorter, or the frame type carries no transmitter address (ACK, CTS).

pub const fn frame_type(&self) -> u8

Frame type (bits 2..4 of frame control): 0 management, 1 control, 2 data.

pub const fn subtype(&self) -> u8

Frame subtype (bits 4..8 of frame control).

pub const fn is_retry(&self) -> bool

Whether the Retry bit is set: the MPDU is a retransmission.

pub const fn has_transmitter(&self) -> bool

Whether the frame carries a transmitter address. ACK and CTS carry only a receiver.

pub const fn sequence_number(&self) -> u16

The 12-bit sequence number.
