Struct RadioTapLayer 

pub struct RadioTapLayer {
    pub index: LayerIndex,
}

RadioTap layer - a zero-copy view into the RadioTap header.

The RadioTap header has a variable length indicated by the it_len field. Present fields are indicated by a bitmask in it_present.

Fields

index: LayerIndex

Implementations

impl RadioTapLayer

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

Create a new RadioTapLayer from start/end offsets.

pub fn validate(buf: &[u8], offset: usize) -> Result<(), FieldError>

Validate the buffer has enough data for a RadioTap header.

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

RadioTap version (always 0).

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

Padding byte.

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

Total header length (little-endian u16).

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

Present flags bitmask (little-endian u32).

pub fn has_field(&self, buf: &[u8], bit: u32) -> bool

Check if a specific present field bit is set.

pub fn has_fcs(&self, buf: &[u8]) -> bool

Check if the FCS flag is set (indicating the payload includes FCS).

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

Parse all present fields from the RadioTap header.
