concordium-rust-sdk 2.3.0

This is the first release of the SDK published in the crates.io package repository.

• https://crates.io/crates/concordium-rust-sdk
• https://docs.rs/concordium-rust-sdk

The following changes are made compared to version 2.2.0.

• Add find_earliest_finalized, find_instance_creation,
  find_first_finalized_block_no_later_than methods to the v2 client.
• Bump MSRV to 1.62
• Add deprecation notices to ModuleRef and Parameter. Use ModuleReference
  and OwnedParameter, respectively, instead.
  • Replace AsRef<Vec<u8>> with AsRef<[u8]> for OwnedParameter (and
    thereby also for the now deprecated Parameter).
    • Migrate from parameter.as_ref(): Use &parameter.as_ref().to_vec() instead.
  • OwnedParameter also has a number of additional methods and trait
    implementations, namely:
  • A from_serial method which constructs a new parameter by serializing the
    input and checking that the length is valid.
  • An empty method which constructs an empty parameter.
  • An Into<Vec<u8>> implementation for getting the inner bytes.
  • An as_parameter method for converting it to the borrowed version
    Parameter(&[u8]) type (not to be confused with the now deprecated
    Parameter(Vec<u8>)).

concordium-rust-sdk 2.2.0

concordium-rust-sdk 2.2.0 (2023-02-06)

This is a minor update that adds a number of quality of life improvements.

• Add helpers to WalletAccount so that it can be constructed from genesis
  account format produced by the genesis creator tool, as well as from browser
  key export format.
• Fix contract schema's to_json to output contract addresses in the correct format.
• Add a Display implementation for ContractEvent.
• Add _single family of functions to Cis2Contract to make it easier to do
  queries and updates for a single token or operator.
• Generalize the signature of Cis2Contract methods that take a block
  identifier. They now take impl IntoBlockIdentifier. All existing uses should
  remain working since &BlockIdentifier implements this trait.
• Add is_rejected_account_transaction helper to BlockItemSummary to help
  extract reject reason for an account transaction.
• Add update_operator_dry_run and transfer_dry_run methods to
  Cis2Contract. These dry-run update_operator and transfer transactions
  using invoke_instance. They can be used to estimate transaction costs, and
  check whether the call will succeed.
• Add is_payday_block helper function to v2::Client to identify whether a specific block is one that includes payday events.
• Add new_from_payload helper to ContractContext for convenience when
  dry-running smart contract update transactions.
• Add a notion of TokenAddress and its string representation based on base58 encoding.

concordium-rust-sdk 2.0.0

This is a major release which breaks compatibility in some areas.

This release adds support for protocol 5, and adds support for GRPC V2. In addition, there are a number of bugfixes and quality of life improvements.

Changelog

• Expose macros for deriving Serial and Deserial from concordium-contracts-common.
• Address method is_alias_of is now is_alias.
• Replaced ReceiveName and InitName with OwnedReceiveName and OwnedContractName from concordium-contracts-common.
• Remove ContractAddress and Address in favor of their equivalents in concordium-contracts-common.
• AccountAddress::new is replaced by a function called account_address_from_registration_id.
• Amount now has a field micro_ccd instead of microgtu.
• The default arithmetic (operator syntax, such as +, -, *) with Amount is now unchecked.
• There are no longer implementations of From<u64> for Amount and From<Amount> for u64 as the behavior of these is not obvious.
  Instead, the functions Amount::from_micro_ccd or Amount::from_ccd and the getter micro_ccd should be used instead.
• Implement Display and FromStr for ContractAddress formatted as <index, subindex>, E.g <145,0>.
• Implement Display and FromStr for Address. The latter attempts to parse a contract address. If this fails it will attempt to parse an AccountAddress.
• Implement FromStr for OwnedReceiveName.
• Remove the From<Vec<u8>> implementation for Parameter. Instead a TryFrom is
  provided that checks the length.
• Add support for the node's GRPC V2 interface.
• Bump minimum supported Rust version to 1.57.
• Add support for CIS0 standard.
• The CIS2 support now uses the V2 node API. This has led so small changes in
  the API.
• Add support for protocol version 5 events and limitations.
• Deprecate add_baker, update_baker_keys, remove_baker,
  update_baker_stake, update_baker_restake_earnings functions. They only
  apply to protocol versions 1-3 and are replaced by configure_baker.
