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.
