Struct Dot11FcsLayer 

pub struct Dot11FcsLayer {
    pub index: LayerIndex,
}

Fields

index: LayerIndex

Implementations

impl Dot11FcsLayer

pub fn new(start: usize, end: usize) -> Self

Create a new Dot11FcsLayer from start/end offsets.

pub fn dot11(&self) -> Dot11Layer

Get the inner Dot11Layer view (excluding FCS).

pub fn fcs(&self, buf: &[u8]) -> Result<u32, FieldError>

Read the FCS field (4 bytes at end of frame, little-endian).

pub fn compute_fcs(data: &[u8]) -> u32

Compute the CRC32 FCS for the frame data (excluding the FCS itself).

pub fn verify_fcs(&self, buf: &[u8]) -> Result<bool, FieldError>

Verify that the FCS matches the frame data.

pub fn frame_type(&self, buf: &[u8]) -> Result<u8, FieldError>

Delegate field access to the inner Dot11Layer.

pub fn subtype(&self, buf: &[u8]) -> Result<u8, FieldError>

pub fn flags(&self, buf: &[u8]) -> Result<u8, FieldError>

pub fn addr1(&self, buf: &[u8]) -> Result<MacAddress, FieldError>

pub fn addr2(&self, buf: &[u8]) -> Result<MacAddress, FieldError>

pub fn addr3(&self, buf: &[u8]) -> Result<MacAddress, FieldError>

pub fn duration(&self, buf: &[u8]) -> Result<u16, FieldError>
