Struct p4rs::packet_in

pub struct packet_in<'a> {
    pub data: &'a [u8],
    pub index: usize,
}

Every packet that goes through a P4 pipeline is represented as a packet_in instance. packet_in objects wrap an underlying mutable data reference that is ultimately rooted in a memory mapped region containing a ring of packets.

Fields

data: &'a [u8]

The underlying data. Owned by an external, memory-mapped packet ring.

index: usize

Extraction index. Everything before index has been extracted already. Only data after index is eligble for extraction. Extraction is always for contiguous segments of the underlying packet ring data.

Implementations

impl<'a> packet_in<'a>

pub fn new(data: &'a [u8]) -> Self

pub fn extract<H: Header>(&mut self, h: &mut H)

pub fn extract_new<H: Header>(&mut self) -> Result<H, TryFromSliceError>

Trait Implementations

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

Formats the value using the given formatter.
