Struct AllSessions

Source 
pub struct AllSessions {
    sessions: HashMap<u128, NonceSession>,
    session_queue: VecDeque<u128>,
    used_ids: HashSet<u128>,
}

Fields§

§sessions: HashMap<u128, NonceSession>§session_queue: VecDeque<u128>§used_ids: HashSet<u128>

store all previously used ids to never use them again reason is that we remove a session in deposit_sign and add it back later, we might create a new one with the same id in between removal and addition

Implementations§

Source§

impl AllSessions

Source

pub fn new() -> Self

Source

pub fn add_new_session_with_id( &mut self, new_nonce_session: NonceSession, id: u128, ) -> Result<(), Report>

Adds a new session to the AllSessions with the given id.. If the current byte size of all sessions exceeds MAX_ALL_SESSIONS_BYTES, the oldest session is removed until the byte size is under the limit.

Source

pub fn add_new_session_with_random_id( &mut self, new_nonce_session: NonceSession, ) -> Result<u128, Report>

Adds a new session to the AllSessions with a random id. Returns the id of the added session.

Source

pub fn remove_session_with_id( &mut self, id: u128, ) -> Result<NonceSession, Report>

Removes a session from the AllSessions with the given id. Also removes it from the session queue, because we might add the session with the same id later (as in [deposit_sign]). Returns the removed session.

Source

fn get_new_unused_id(&mut self) -> u128

Generates a new unused id for a nonce session. The important thing it that the id not easily predictable.

Source

fn remove_oldest_session(&mut self) -> Result<usize, Report>

Removes the oldest session from the AllSessions. Returns the number of bytes removed.

Source

fn session_bytes(session: &NonceSession) -> Result<usize, Report>

Source

pub fn total_sessions_byte_size(&self) -> Result<usize, Report>

Returns the total byte size of all secnonces in the AllSessions.
