Required Methods

fn generate_new_token( &mut self, context: &mut Context<'_>, source_connection_id: &LocalId, output_buffer: &mut [u8] ) -> Option<()>

Generate a signed token to be delivered in a NEW_TOKEN frame. This function will only be called if the provider support NEW_TOKEN frames.

fn generate_retry_token( &mut self, context: &mut Context<'_>, original_destination_connection_id: &InitialId, output_buffer: &mut [u8] ) -> Option<()>

Generate a signed token to be delivered in a Retry Packet

fn validate_token( &mut self, context: &mut Context<'_>, token: &[u8] ) -> Option<InitialId>

Return the original destination connection id of a valid token. If the token is invalid, return None. Callers should detect duplicate tokens and treat them as invalid.

Object Safety

This trait is not object safe.
