Enum PacketPayload 

#[non_exhaustive]
pub enum PacketPayload {
    Owned(Vec<u8>),
    Shared {
        bytes: Arc<[u8]>,
        start: usize,
        len: usize,
    },
    Accounted(SharedStorage<u8>),
}

Where a packet’s bytes live.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Owned(Vec<u8>)

Bytes the packet owns.

Shared

len bytes of bytes starting at start.

Fields

bytes: Arc<[u8]>

The shared buffer.

start: usize

First byte of the payload.

len: usize

Payload length.

Accounted(SharedStorage<u8>)

Admitted storage. Clones and subviews retain the backing allocation’s charge until its last owner drops.

Implementations

impl PacketPayload

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

The payload bytes.

pub fn len(&self) -> usize

Payload length in bytes.

pub fn is_empty(&self) -> bool

Whether the payload is empty.

pub fn into_vec(self) -> Vec<u8>

The payload as an ordinary, unaccounted vector: free for Owned, a copy for Shared and Accounted. The copy is outside a storage budget. Budget-enforcing adapters keep the accounted payload instead of calling this legacy ownership bridge.

Trait Implementations

impl Clone for PacketPayload

fn clone(&self) -> PacketPayload

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PacketPayload

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

Formats the value using the given formatter.
