librustzcash/zcash_keys/CHANGELOG.md

All notable changes to this library will be documented in this file.

The format is based on Keep a Changelog, and this library adheres to Rust's notion of Semantic Versioning.

[Unreleased]

Added

• zcash_keys::address::Address::has_receiver
• impl Display for zcash_keys::keys::AddressGenerationError
• impl std::error::Error for zcash_keys::keys::AddressGenerationError

Changed

• zcash_keys::keys::AddressGenerationError has a new variant DiversifierSpaceExhausted
• zcash_keys::keys::UnifiedFullViewingKey::{find_address, default_address} now return Result<(UnifiedAddress, DiversifierIndex), AddressGenerationError> instead of Option<(UnifiedAddress, DiversifierIndex)>

[0.1.1] - 2024-03-04

Added

• zcash_keys::keys::UnifiedAddressRequest::all

Fixed

• A missing application of the sapling feature flag was remedied; prior to this fix it was not possible to use this crate without the sapling feature enabled.

[0.1.0] - 2024-03-01

The entries below are relative to the zcash_client_backend crate as of zcash_client_backend 0.10.0.

Added

• zcash_keys::address (moved from zcash_client_backend::address). Further additions to this module:
  • UnifiedAddress::{has_orchard, has_sapling, has_transparent}
  • UnifiedAddress::receiver_types
  • UnifiedAddress::unknown
• zcash_keys::encoding (moved from zcash_client_backend::encoding).
• zcash_keys::keys (moved from zcash_client_backend::keys). Further additions to this module:
  • AddressGenerationError
  • UnifiedAddressRequest
• A new orchard feature flag has been added to make it possible to build client code without orchard dependendencies.

Changed

• The following methods and enum variants have been placed behind an orchard feature flag:
  • zcash_keys::address::UnifiedAddress::orchard
  • zcash_keys::keys::DerivationError::Orchard
  • zcash_keys::keys::UnifiedSpendingKey::orchard
• zcash_keys::address:
  • RecipientAddress has been renamed to Address.
  • Address::Shielded has been renamed to Address::Sapling.
  • UnifiedAddress::from_receivers no longer takes an Orchard receiver argument unless the orchard feature is enabled.
• zcash_keys::keys:
  • UnifiedSpendingKey::address now takes an argument that specifies the receivers to be generated in the resulting address. Also, it now returns Result<UnifiedAddress, AddressGenerationError> instead of Option<UnifiedAddress> so that we may better report to the user how address generation has failed.
  • UnifiedSpendingKey::transparent is now only available when the transparent-inputs feature is enabled.
  • UnifiedFullViewingKey::new no longer takes an Orchard full viewing key argument unless the orchard feature is enabled.

Removed

• zcash_keys::address::AddressMetadata (use zcash_client_backend::data_api::TransparentAddressMetadata instead).
