Struct RawLayer 

pub struct RawLayer {
    pub index: LayerIndex,
}

A layer representing raw (unparsed) payload data.

The Raw layer is the simplest layer type - it just holds arbitrary bytes without any protocol-specific parsing. It’s typically found at the end of a packet after all known protocols have been parsed.

Fields

index: LayerIndex

The layer’s position within the packet buffer.

Implementations

impl RawLayer

pub fn new(index: LayerIndex) -> Self

Create a new RawLayer with the given index.

pub fn from_start(start: usize) -> Self

Create a RawLayer that spans the entire buffer from start to the end.

pub fn load<'a>(&self, buf: &'a [u8]) -> &'a [u8]

Get the raw bytes of this layer.

pub fn len(&self, buf: &[u8]) -> usize

Get the length of the raw payload.

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

Check if the payload is empty.

pub fn summary(&self, buf: &[u8]) -> String

Get a summary string for this layer.

pub fn header_len(&self, buf: &[u8]) -> usize

Get the header length (for Raw, this is the entire payload).

pub fn hex_preview(&self, buf: &[u8], max_bytes: usize) -> String

Get a hexdump preview of the payload (first N bytes).

pub fn ascii_preview(&self, buf: &[u8], max_bytes: usize) -> String

Get an ASCII preview of the payload (printable chars only).

pub fn hashret(&self, buf: &[u8]) -> Vec<u8>

Compute a hash for request/response matching. For Raw, we just return the first 8 bytes as a simple hash.

pub fn answers(&self, buf: &[u8], other: &RawLayer, other_buf: &[u8]) -> bool

Check if this Raw layer “answers” another Raw layer. For Raw payloads, we consider them matching if they have the same content.

pub fn get_field( &self, buf: &[u8], name: &str, ) -> Option<Result<FieldValue, FieldError>>

Get a field value by name.

pub fn set_field( &self, buf: &mut [u8], name: &str, value: FieldValue, ) -> Option<Result<(), FieldError>>

Set a field value by name.

pub fn field_names() -> &'static [&'static str]

Get the list of field names for this layer.
