pub struct NullifierBlock(/* private fields */);Expand description
The BlockNumber at which a Nullifier was consumed.
Since there are no nullifiers in the genesis block the BlockNumber::GENESIS is used to
signal an unconsumed nullifier.
This type can be converted to a Word which is laid out like this:
[block_num, 0, 0, 0]Implementations§
Source§impl NullifierBlock
impl NullifierBlock
pub const UNSPENT: NullifierBlock
Sourcepub fn new(word: Word) -> Result<Self, NullifierTreeError>
pub fn new(word: Word) -> Result<Self, NullifierTreeError>
Returns a new NullifierBlock constructed from the provided word.
§Errors
Returns an error if:
- The 0th element in the word is not a valid BlockNumber.
- Any of the remaining elements is non-zero.
Sourcepub fn is_unspent(&self) -> bool
pub fn is_unspent(&self) -> bool
Returns true if the nullifier has not yet been spent.
