Crate casperlabs_types 

Types used to allow creation of Wasm contracts and tests for use on the CasperLabs Platform.

no_std

By default, the library is no_std, however you can enable full std functionality by enabling the crate’s std feature.

Modules

account

Contains types and constants associated with user accounts.

api_error

Contains ApiError and associated helper functions.

bytesrepr

Contains serialization and deserialization code for types used throughout the system.

contracts

Data types for supporting contract headers feature.

runtime_args

Home of RuntimeArgs for calling contracts

system_contract_errors

Home of error types returned by system contracts.

system_contract_type

Home of system contract type enum.

Macros

runtime_args

Macro that makes it easier to construct named arguments.

Structs

AccessRights

A struct which behaves like a set of bitflags to define access rights associated with a URef.

BlockTime

A newtype wrapping a u64 which represents the block time.

CLTypeMismatch

Error while converting a CLValue into a given type.

CLValue

A CasperLabs value, i.e. a value which can be stored and manipulated by smart contracts.

ContractWasm

A container for contract’s WASM bytes.

ProtocolVersion

A newtype wrapping a SemVer which represents a CasperLabs Platform protocol version.

SemVer

A struct for semantic versioning.

U128

Little-endian large integer type

U256

Little-endian large integer type

U512

Little-endian large integer type

URef

Represents an unforgeable reference, containing an address in the network’s global storage and the AccessRights of the reference.

Enums

ApiError

Errors which can be encountered while running a smart contract.

CLType

CasperLabs types, i.e. types which can be stored and manipulated by smart contracts.

CLValueError

Error relating to CLValue operations.

Key

The type under which data (e.g. CLValues, smart contracts, user accounts) are indexed on the network.

Phase

The phase in which a given contract is executing.

TransferredTo

The result of a successful transfer between purses.

UIntParseError

Error type for parsing U128, U256, U512 from a string.

VersionCheckResult

The result of ProtocolVersion::check_next_version.

Constants

SEM_VER_SERIALIZED_LENGTH

Length of SemVer when serialized

UREF_ADDR_LENGTH

The number of bytes in a URef address.

UREF_SERIALIZED_LENGTH

The number of bytes in a serialized URef where the AccessRights are not None.

Traits

CLTyped

A type which can be described as a CLType.

Functions

named_key_type

Returns the CLType describing a “named key” on the system, i.e. a (String, Key).
