Modules
- Definitions and utilities for ink! smart contract static reflection.
Macros
- Computes and expands into the BLAKE2b 256-bit hash of the string input.
- Generates a wrapper which can be used for interacting with the contract.
- Computes the ink! selector of the string and expands into its byte representation.
- Computes the ink! selector of the string and expands into its
u32
representation.
Structs
- The API behind the
self.env()
andSelf::env()
syntax in ink!. - Represents some abstract value that is returned by a function. Currently acts as a placeholder.
Enums
- An error emitted by the smart contracting language.
Traits
- Trait implemented by chain extensions.
- Only implemented for
ValueReturned
. - Implemented by contracts that are compiled as dependencies.
- Implementors return their meta type information.
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 (likeMapping
,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.
