Release concordium-std-derive 3.1.0

concordium-std-derive 3.1.0 (2022-08-04)

• Removed derive(Serial) and derive(Deserial) (moved to concordium-contracts-common-derive).

Release concordium-std 3.0.0

concordium-std 3.0.0 (2022-05-17)

• Remove support for v0 smart contracts and add support for v1:
  • Replace message passing with synchronous calls:
    • Remove the Action type.
    • Add HasHost, which has (synchronous) functions for making
      transfers, invoke_transfer, and calling other contracts, invoke_contract.
  • Enable arbitary, serializable, return values for contract functions.
  • Overhaul test infrastructure to support v1 contracts:
    • Add ability to mock contract invocations.
    • Add a number of helper functions and types to ease testing.
  • Change of the contract state works
    • Make the state a tree of byte arrays instead of a bytearray.
    • Remove the 16kb limit to state size.
    • Introduce high-level abstractions over the new state, including the
      StateBuilder, StateMap, StateSet, and StateBox.
    • Add new traits for the low-level state interaction: HasStateApi and HasStateEntry.
  • The Seek trait now works with i32 instead of i64. This is more efficient,
    and sufficient for the target architecture.
• Expose the module of primitive host functions with an unsafe API.
• Add cryptographic primitives:
  • Add a new attribute crypto-primitives (on both init and receive functions), which gives the function an additional parameter, &impl HasCryptoPrimitives.
  • Add the trait HasCryptoPrimitives with two implementations (host-backed + test).
  • For the test implementation, the default option uses mocks. But the actual implementations can be used if you enable the feature crypto-primitives.
  • Add new feature flag crypto-primitives.

Release concordium-std-derive 3.0.0

concordium-std-derive 3.0.0 (2022-05-17)

• Add #[concordium_cfg_not_test] macro, that excludes parts of code for testing.
• Add derive(Deletable) macro for deriving the Deletable trait.
• Add derive(DeserialWithState) macro.
• Change receive and init macros to support the new V1 contract state and
  sync calls.

Release concordium-std 2.0.0

concordium-std 2.0.0 (2022-01-05)

• Update references to token to match token name (CCD).
• Improve claim_eq and claim_ne macros such that:
  • Arguments are only evaluated once.
  • Type inference works as you would expect.

Release concordium-std-derive 2.0.0

concordium-std-derive 2.0.0 (2022-01-05)

• Update references to token to match token name (CCD).

Release concordium-std 1.0.0

concordium-std 1.0.0 (2021-10-05)

• Add error codes for the new cases in NewContractNameError and NewReceiveNameError:
  • NewContractNameError::ContainsDot is mapped to i32::MIN + 9
  • NewContractNameError::InvalidCharacters is mapped to i32::MIN + 10
  • NewReceiveNameError::InvalidCharacters is mapped to i32::MIN + 11
• Change error code for when a contract that was not marked as payable received
  tokens. The error code is now i32::MIN + 12, changed from the previous -1.
• Export HashMap and HashSet from contract-common in collections module.
• Added implementation of SerialCtx for Vec.
• Export Box when no std feature.
• Bump minimum supported Rust version to 1.51.
• Deriving SchemaType supports types with generics.

Release concordium-std-derive 1.0.0

concordium-std-derive 1.0.0 (2021-10-05)

• Validate contract and receive names
• Improve precision of error locations in init and receive_workers
• Improve precision of error locations for size_length
• Unify the map_size_length, set_size_length, and string_size_length
  into size_length.
• Make ensure_ordered work without having to specify a size length.

Release concordium-std 0.5.0

concordium-std 0.5.0 (2021-05-12)

• Make Write implementation for ContractStateTest resize the state automatically
  to be consistent with the Write implementation for ContractState.
• Use little-endian encoding for sender contract addresses in receive contexts. This
  reverts the change in concordium-std 0.4.1.
• Change the receive_name parameter of HasActions::send to use ReceiveName
  instead of str.
• Rename send to send_raw in HasActions.
• Rename log_bytes to log_raw in HasLogger.
• Add send, a wrapper for HasActions::send_raw, which automatically
  serializes parameter (using Serial).
• Allow init and receive methods to return custom error codes that will be displayed to the user
  if a smart-contract invocation fails.
• Add i128 and u128 support to serialization and schema.

Release concordium-std-derive 0.5.0

concordium-std-derive 0.5.0 (2021-05-12)

• Add macros for deriving error implementations.
• Make derive macros slightly more hygienic.
