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. contract_ref_from_path Generates a wrapper which can be used for interacting with the contract. keccak_256 Computes the Keccak-256 hash of the given string. 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. LangError An error emitted by the smart contracting language. IIP2_WILDCARD_COMPLEMENT_SELECTOR A well known selector reserved for the message required to be defined
alongside a wildcard selector. See IIP-2 . CONTRACT_ERRORS_SOL Any error which derives #[derive(ink::SolErrorMetadata)] and is used in the contract
binary will have its implementation added to this distributed slice at linking time. 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. 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_errors_sol Collect the Solidity ABI compatible metadata of all error definitions encoded as
Solidity custom errors that are linked and used in the binary. 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. 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.
