Trait ConnectionIdGenerator 

Source 
pub trait ConnectionIdGenerator<'a>: Send + 'static {
    // Required methods
    fn new_connection_id(&self, socket_cookie: u64) -> ConnectionId<'a>;
    fn verify_connection_id(
        &self,
        socket_cookie: u64,
        cid: &ConnectionId<'_>,
    ) -> QuicResult<()>;
}
Expand description

A customizable generator to derive and verify QUIC connection IDs.

For QUIC servers, it can be useful to encode additional information in the source connection ID. This trait allows users to implement their own logic for that purpose. The crate also provides SimpleConnectionIdGenerator if no such customization is needed.

Clients currently can’t configure a ConnectionIdGenerator and always use the SimpleConnectionIdGenerator.

Required Methods§

Source

fn new_connection_id(&self, socket_cookie: u64) -> ConnectionId<'a>

Creates a new ConnectionId according to the generator’s logic.

The socket_cookie is propagated unchanged from the QuicListener that received the connection.

Source

fn verify_connection_id( &self, socket_cookie: u64, cid: &ConnectionId<'_>, ) -> QuicResult<()>

Verifies whether cid was generated by this ConnectionIdGenerator.

socket_cookie matches the value that would have been passed to new_connection_id calls. The method should return an Err variant if the connection ID can’t be verified.
