Implemented by contracts that are compiled as dependencies.

Attribute Macros

Defines the interface for a chain extension.
Entry point for writing ink! smart contracts.
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.
Defines a unit test that makes use of ink!’s off-chain testing capabilities.
Marks trait definitions to ink! as special ink! trait definitions.
