Struct EthernetReader

pub struct EthernetReader<'a> {
    pub bytes: &'a [u8],
    /* private fields */
}

Reads Ethernet header fields.

Fields

bytes: &'a [u8]

Implementations

impl<'a> EthernetReader<'a>

pub fn new(bytes: &'a [u8]) -> Result<Self, &'static str>

Creates a new EthernetReader from the given slice.

pub fn calculate_header_len(bytes: &[u8]) -> Result<usize, &'static str>

Calculates the header length of an Ethernet frame.

Depending on the presence of VLAN tagging, the header length may vary.

pub fn is_vlan_tagged(bytes: &[u8]) -> bool

Checks if the Ethernet frame is VLAN tagged.

pub fn is_vlan_double_tagged(bytes: &[u8]) -> bool

Checks if the Ethernet frame is double VLAN tagged (Q-in-Q).

pub fn dest_mac(&self) -> &[u8]

Returns the destination MAC address field.

pub fn src_mac(&self) -> &[u8]

Returns the source MAC address field.

pub fn ethertype(&self) -> u16

Returns the EtherType field field.

Indicates which network protocol is encapsulated.

pub fn vlan_tag(&self) -> Option<(u16, u16)>

Returns the VLAN tag.

Optionally present in the Ethernet frame header.

pub fn double_vlan_tag(&self) -> Option<((u16, u16), (u16, u16))>

Returns the double VLAN tag (Q-in-Q).

Optionally present in the Ethernet frame header.

pub const fn header_len(&self) -> usize

Returns the header length in bytes.

pub fn header(&self) -> &'a [u8]

Returns a reference to the header.

pub fn payload(&self) -> &[u8]

Returns a reference to the payload.

Trait Implementations

impl Debug for EthernetReader<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> ParseReader<'a> for EthernetReader<'a>

fn parse(bytes: &'a [u8]) -> Result<Self, &'static str>

Parses an Ethernet frame from a byte slice.

Validates that the byte slice is at least the minimum Ethernet frame length.

impl<'a> PartialEq for EthernetReader<'a>

fn eq(&self, other: &EthernetReader<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
