Function LazyTowerHashChainProofBuilder

LazyTowerHashChainProofBuilder(H, W, hash?): {
    add: ((item) => void);
    build: ((idx) => LazyTowerHashChainProof);
    indexOf: ((item) => number);
}
LazyTowerHashChainProofBuilder is a TypeScript implementation of LazyTower to generate proofs of membership.
Parameters
- H: number
  Height of tower of the proving circuit. It can be less than the H in the contract.
- W: number
  Width of tower.
- hash: ((a, b) => bigint) = defaultHash
  A hash function which supports 2 input values.
  - - (a, b): bigint
    - Parameters
      a: bigint
      b: bigint
      Returns bigint
Returns {
    add: ((item) => void);
    build: ((idx) => LazyTowerHashChainProof);
    indexOf: ((item) => number);
}
- add: ((item) => void)
  - - (item): void
    - Adds a new item in the LazyTower.
      Parameters
      item: bigint
      Item to be added.
      Returns void
- build: ((idx) => LazyTowerHashChainProof)
  - - (idx): LazyTowerHashChainProof
    - Builds a proof of membership.
      Parameters
      idx: number
      Index of the proof's item.
      Returns LazyTowerHashChainProof
      Proof object.
- indexOf: ((item) => number)
  - - (item): number
    - Returns the index of a item. If the item does not exist it returns -1.
      Parameters
      item: bigint
      Added item.
      Returns number
      Index of the item.
