Overview

The UniquePayments struct manages a collection of payment transactions. It is designed to store and manipulate unique payment entries, ensuring no duplicates are recorded.

Types

• PaymentsVec<M>: A managed vector of ESDT token payments specific to the MultiversX blockchain.

Structs

• UniquePayments<M>
  • Stores unique payments in a managed vector.

Implementation

• Default for UniquePayments<M>
  • Provides a default instantiation of UniquePayments, which contains an empty vector of payments.
• new() -> Self
  • Creates a new instance of UniquePayments.
• new_from_unique_payments(payments: PaymentsVec<M>) -> Self
  • Creates a new instance of UniquePayments from an existing vector of unique payments.
• new_from_payments(payments: PaymentsVec<M>) -> Self
  • Constructs a UniquePayments instance by merging payments into a unique collection.

Methods

• add_payment(p: &EsdtTokenPayment<M>)
  • Adds a payment to the collection, ensuring uniqueness.
• withdraw_payments(payment: &EsdtTokenPayment<M>)
  • Removes a payment from the collection.

Usage

• The UniquePayments struct is instantiated with either the new, new_from_unique_payments, or new_from_payments methods.
• The add_payment method allows adding new payment entries while maintaining the uniqueness of the payments vector.
