Implementations

impl EthernetLayer

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

pub const fn at_start() -> Self

pub const fn at_offset(offset: usize) -> Self

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

pub fn dispatch(buf: &[u8], offset: usize) -> EthernetFrameType

Dispatch hook: returns appropriate layer type based on type/length field

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

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

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

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

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

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

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

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

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

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

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

Compute hash for packet matching. Returns type field + payload hash for matching request/response pairs.

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

Check if this packet answers another. For Ethernet, this delegates to payload matching.

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

Extract padding (Ethernet II has no padding concept at this layer)

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

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

pub fn next_layer(&self, buf: &[u8]) -> Option<LayerKind>

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

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

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

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

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

pub fn ethertype_name(&self, buf: &[u8]) -> &'static str

Get EtherType name

pub fn route(&self, _buf: &[u8]) -> Option<String>
