Struct PacketPool 

pub struct PacketPool { /* private fields */ }

Pool of packet builders for amortized allocation.

Uses counter-based nonces for zero-allocation packet construction. All builders in the pool share a single TX counter to prevent nonce reuse.

Implementations

impl PacketPool

pub fn new(size: usize, key: &[u8; 32], session_id: u64) -> Self

Create a new packet pool

pub fn with_origin( size: usize, key: &[u8; 32], session_id: u64, origin_hash: u64, ) -> Self

Create a new packet pool with origin identity

pub fn set_key(&mut self, key: &[u8; 32], session_id: u64)

Update the encryption key and session ID.

Drains all pooled builders so that no stale builder can encrypt with the old key while sharing a counter that restarted at zero (which would cause nonce reuse and break ChaCha20-Poly1305). Builders are lazily re-created with the new key on the next get().

pub fn get(&self) -> PooledBuilder<'_>

Get a builder from the pool

pub fn capacity(&self) -> usize

Get the pool capacity

pub fn available(&self) -> usize

Get the number of available builders

pub fn session_id(&self) -> u64

Get the session ID

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