Struct plasma_cash_token::Token

pub struct Token<TxnType, HashType> where
    TxnType: PlasmaCashTxn<HashType>,
    HashType: AsRef<[u8]>,  {
    pub uid: BitVec,
    pub status: TokenStatus,
    pub history: Vec<TxnType>,
    pub proofs: Vec<Vec<HashType>>,
}

Token storage type that performs history verification and challenge detection for a given token.

Can be serialized for wire transmission and data storage purposes.

Example

Users of this API should should define this e.g.

let t: Token<Transaction, H256> = Token::new(uid); // `uid` is BitVec

Fields

uid: BitVec

status: TokenStatus

history: Vec<TxnType>

proofs: Vec<Vec<HashType>>

Methods

impl<'a, TxnType, HashType> Token<TxnType, HashType> where
    TxnType: PlasmaCashTxn<HashType>,
    HashType: AsRef<[u8]>, 

pub fn new(uid: BitVec) -> Token<TxnType, HashType>

Create new token with given uid stored on the rootchain. (history is empty to start)

pub fn is_valid(&self) -> bool

Validate history of token is consistent

pub fn add_transaction(&mut self, txn: TxnType) -> Result<(), &'static str>

Add a new transaction to the history. Must first pass validation that new transaction follows old one.
