Struct quinn_proto::HashedConnectionIdGenerator

pub struct HashedConnectionIdGenerator { /* private fields */ }

Generates 8-byte connection IDs that can be efficiently validated

This generator uses a non-cryptographic hash and can therefore still be spoofed, but nonetheless helps prevents Quinn from responding to non-QUIC packets at very low cost.

Implementations

impl HashedConnectionIdGenerator

pub fn new() -> Self

Create a generator with a random key

pub fn from_key(key: u64) -> Self

Create a generator with a specific key

Allows validate to recognize a consistent set of connection IDs across restarts

pub fn set_lifetime(&mut self, d: Duration) -> &mut Self

Set the lifetime of CIDs created by this generator

Trait Implementations

impl ConnectionIdGenerator for HashedConnectionIdGenerator

fn generate_cid(&mut self) -> ConnectionId

Generates a new CID

fn validate(&self, cid: &ConnectionId) -> Result<(), InvalidCid>

Quickly determine whether cid could have been generated by this generator

fn cid_len(&self) -> usize

Returns the length of a CID for connections created by this generator

fn cid_lifetime(&self) -> Option<Duration>

Returns the lifetime of generated Connection IDs

impl Default for HashedConnectionIdGenerator

fn default() -> Self

Returns the “default value” for a type.
