Struct Mbuf 

pub struct Mbuf { /* private fields */ }

A memory buffer for packet data

Mbufs are the basic unit for carrying packet data in DPDK. They are allocated from memory pools and contain both metadata and actual packet data.

Implementations

impl Mbuf

pub unsafe fn from_raw(ptr: *mut rte_mbuf) -> Option<Self>

Create a new Mbuf from a raw pointer

Safety

The caller must ensure:

• The pointer is valid and properly aligned
• The mbuf was allocated from a valid mempool
• Ownership is being transferred (the raw pointer should not be freed elsewhere)

pub fn as_raw(&self) -> *mut rte_mbuf

Get the raw pointer to the underlying mbuf

pub fn into_raw(self) -> *mut rte_mbuf

Consume self and return the raw pointer

After calling this, the caller is responsible for freeing the mbuf

pub fn data_offset(&self) -> u16

Get the data offset within the buffer

pub fn packet_len(&self) -> u32

Get the total packet length

pub fn data_len(&self) -> u16

Get the data length in this segment

pub fn buf_len(&self) -> u16

Get the buffer length (total available space)

pub fn data(&self) -> Option<&[u8]>

Get a slice to the packet data

Returns None if the buffer address is null

pub fn data_mut(&mut self) -> Option<&mut [u8]>

Get a mutable slice to the packet data

Returns None if the buffer address is null

pub fn set_data_len(&mut self, len: u16)

Set the data length

pub fn set_packet_len(&mut self, len: u32)

Set the packet length
