pub struct SpendingCounter(u32);
Expand description

Spending counter associated to an account.

every time the owner is spending from an account, the counter is incremented. A matching counter needs to be used in the spending phase to make sure we have non-replayability of a transaction.

Note that the leading LANES_BITS bits are used to codify the implicit lane.

Implementations§

impl SpendingCounter

source

pub fn lane(self) -> usize

source

pub fn unlaned_counter(self) -> u32

source

pub fn new(lane: usize, counter: u32) -> Result<SpendingCounter, Error>

source

pub fn zero() -> SpendingCounter

source

pub fn increment(self) -> SpendingCounter

Increment the counter within it own lane. the lane of where this counter apply, cannot change through the incrementation procedure

if the counter bits overflow, it will automatically be wrapped, so that the lane remains identical

pub fn increment_nth(self, n: u32) -> SpendingCounter

source

pub fn to_bytes(self) -> [u8; 4]

source

pub fn from_bytes(bytes: [u8; 4]) -> SpendingCounter
