Crate ink Copy item path Source pub extern crate polkavm_derive;pub use ink_env as env;pub use ink_metadata as metadata;pub use ink_prelude as prelude;pub use ink_primitives as primitives;pub use scale;pub use scale_info;pub use xcm;abi Abstractions for ABI representation and encoding/decoding. codegen Definitions and facilities mainly used by the ink! codegen. reflect Definitions and utilities for ink! smart contract static reflection. sol Abstractions for implementing Solidity ABI encoding/decoding for arbitrary Rust types. storage blake2x256 Computes and expands into the BLAKE2b 256-bit hash of the string input. combine_extensions Macro defines the combined chain extension via structure definition.
Each sub-extension can be accessed by the corresponding field. contract_ref Generates a wrapper which can be used for interacting with the contract. message_builder Creates an instance of a message builder for an #[ink::trait_definition]. 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. sol_error_selector Returns the selector of the equivalent Solidity custom error
for given the name (as a const expression) and a tuple type
representing the error parameters types. EnvAccess The API behind the self.env() and Self::env() syntax in ink!. H160 Fixed-size uninterpreted hash type with 20 bytes (160 bits) size. H256 Fixed-size uninterpreted hash type with 32 bytes (256 bits) size. U256 Little-endian large integer type
256-bit unsigned integer. ValueReturned Represents some abstract value that is returned by a function.
Currently acts as a placeholder. LangError An error emitted by the smart contracting language. IIP2_WILDCARD_COMPLEMENT_SELECTOR A well know selector reserved for the message required to be defined
alongside a wildcard selector. See IIP-2 . CONTRACT_EVENTS Any event which derives #[derive(ink::EventMetadata)] and is used in the contract
binary will have its implementation added to this distributed slice at linking time. ChainExtensionInstance Trait implemented by chain extensions. Output Only implemented for ValueReturned SolDecode Maps an arbitrary Rust/ink! type to a Solidity ABI type equivalent for Solidity
ABI decoding. SolEncode Maps an arbitrary Rust/ink! type to a Solidity ABI type equivalent for Solidity
ABI encoding. ToAddr Implemented by contracts that are compiled as dependencies. collect_events Collect the [EventSpec] metadata of all event definitions linked and used in the
binary. Address A Solidity compatible address type. ConstructorResult The Result type for ink! constructors. MessageResult The Result type for ink! messages. 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. 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.
