Crate ink_macro

Macros§

blake2x256: Computes and expands into the BLAKE2b 256-bit hash of the string input.
selector_bytes: Computes the ink! selector of the string and expands into its byte representation.
selector_id: Computes the ink! selector of the string and expands into its u32 representation.

chain_extension: Defines the interface for a chain extension.
contract: Entry point for writing ink! smart contracts.
event: Implements the necessary traits for a struct to be emitted as an event from a contract.
scale_derive: Derive the re-exported traits ink::scale::Encode, ink::scale::Decode and ink::scale_info::TypeInfo. It enables using the built in derive macros for these traits without depending directly on the parity-scale-codec and scale-info crates.
storage_item: Prepares the type to be fully compatible and usable with the storage. It implements all necessary traits and calculates the storage key for types. Packed types don’t have a storage key, but non-packed types (like Mapping, Lazy etc.) require calculating the storage key during compilation.
test: Defines a unit test that makes use of ink!’s off-chain testing capabilities.
trait_definition: Marks trait definitions to ink! as special ink! trait definitions.

Event: Derives an implementation of the [ink::Event] trait for the given struct.
EventMetadata: Derives the [ink::EventMetadata] trait for the given struct, which provides metadata about the event definition.
Storable: Derives ink::storage’s Storable trait for the given struct, enum or union.
StorableHint: Derives ink::storage’s StorableHint trait for the given struct or enum.
StorageKey: Derives ink::storage’s StorageKey trait for the given struct or enum.
StorageLayout: Derives ink::storage’s StorageLayout trait for the given struct or enum.
