pub struct Packet { /* private fields */ }

Implementations

impl Packet

pub fn new(headroom: usize, capacity: usize) -> Self

pub fn with_headroom(headroom: usize) -> Self

pub fn with_capacity(capacity: usize) -> Self

pub fn headroom(&self) -> usize

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn push_hdr<T: AsBytes>(&self) -> Hdr<T>

Append a new header to the packet

pub fn push<T: AsBytes>(&self, item: T) -> Hdr<T>

Append a new header to the packet and initialize it

pub fn push_bytes<T: AsRef<[u8]>>(&self, bytes: T) -> PktSlice

Append a bunch of bytes and return their offset

pub fn push_slice(&self, len: usize) -> PktSlice

Expand the packet by len bytes and return a handle to the bytes

pub fn as_slice(&self) -> PktSlice

Return the entire packet as a slice handle

pub fn lower_headroom<T: AsBytes>(&mut self) -> Hdr<T>

Prepend a new header into the packet headroom

pub fn lower_headroom_for<T: AsBytes>(&mut self, item: T) -> Hdr<T>

Prepend a new header into the packet headroom

pub fn return_headroom<T: AsBytes>(&mut self, hdr: Hdr<T>)

Return headroom to the packet. Header must start at the first byte of packet buffer

pub fn to_vec(&self) -> Vec<u8>

pub fn to_vec_from(&self, ps: PktSlice) -> Vec<u8>

pub fn into_vec_from(self, ps: PktSlice) -> Vec<u8>

Trait Implementations

impl Clone for Packet

fn clone(&self) -> Packet

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Packet

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

Formats the value using the given formatter.

impl Default for Packet

fn default() -> Self

Returns the “default value” for a type.

impl From<Packet> for Vec<u8>

fn from(p: Packet) -> Self

Converts to this type from the input type.

impl PartialEq for Packet

fn eq(&self, other: &Packet) -> 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.
