Crate ink_macro Copy item path Source 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. contract Entry point for writing ink! smart contracts. contract_ref Defines the interface of a “callee” contract and generates a wrapper type which can be
used for interacting with the contract. error Implements the necessary traits for ABI encoding/decoding this type as revert error
data. 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. SolDecode Derives an implementation of ink::SolDecode
for the given struct or enum. SolEncode Derives an implementation of ink::SolEncode
for the given struct or enum. SolErrorDecode Derives an implementation of ink::sol::SolErrorDecode
for the given struct or enum. SolErrorEncode Derives an implementation of ink::sol::SolErrorEncode
for the given struct or enum. SolErrorMetadata Derives an implementation of ink::metadata::sol::SolErrorMetadata
for the given struct or enum. 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.
