Crate casper_types[−][src]
Expand description
Types used to allow creation of Wasm contracts and tests for use on the Casper Platform.
no_std
By default, the library is no_std, however you can enable full std functionality by enabling
the crate’s std feature.
Re-exports
pub use crypto::*;Modules
Contains types and constants associated with user accounts.
Contains ApiError and associated helper functions.
Contains serialization and deserialization code for types used throughout the system.
Data types for supporting contract headers feature.
Cryptographic types and operations on them
Home of RuntimeArgs for calling contracts
System modules, formerly known as “system contracts”
Macros
Macro that makes it easier to construct named arguments.
Structs
A struct which behaves like a set of bitflags to define access rights associated with a
URef.
A newtype wrapping a u64 which represents the block time.
Error while converting a CLValue into a given type.
A Casper value, i.e. a value which can be stored and manipulated by smart contracts.
Methods and type signatures supported by a contract.
A newtype wrapping a HashAddr which is the raw bytes of
the ContractHash
Contract definition, metadata, and security container.
A newtype wrapping a HashAddr which is the raw bytes of
the ContractPackageHash
Major element of ProtocolVersion combined with ContractVersion.
A container for contract’s WASM bytes.
A newtype wrapping a HashAddr which is the raw bytes of
the ContractWasmHash
A newtype wrapping a [u8; DEPLOY_HASH_LENGTH] which is the raw bytes of the
deploy hash.
Information relating to the given Deploy.
Type signature of a method. Order of arguments matter since can be referenced by index as well as name.
Collection of named entry points
Era ID newtype.
The effect of executing a single deploy.
A (labelled) “user group”. Each method of a versioned contract may be associated with one or more user groups which are allowed to call it.
Named arguments to a contract
A named key.
An operation performed while executing a deploy.
Parameter to a method
A newtype wrapping a SemVer which represents a Casper Platform protocol version.
Represents a collection of arguments passed to a smart contract.
A struct for semantic versioning.
Represents a transfer from one purse to another
A newtype wrapping a [u8; TRANSFER_ADDR_LENGTH] which is the raw bytes of the
transfer address.
A transformation performed while executing a deploy.
Little-endian large integer type
Little-endian large integer type
Little-endian large integer type
Represents an unforgeable reference, containing an address in the network’s global storage and
the AccessRights of the reference.
Enums
Errors which can be encountered while running a smart contract.
Casper types, i.e. types which can be stored and manipulated by smart contracts.
Error relating to CLValue operations.
Enum describing the possible access control options for a contract entry point (method).
Context of method execution
The result of executing a single deploy.
The type under which data (e.g. CLValues, smart contracts, user accounts)
are indexed on the network.
The type of operation performed while executing a deploy.
Parsing error when creating a SemVer.
The phase in which a given contract is executing.
Error returned when decoding a TransferAddr from a formatted string.
The result of a successful transfer between purses.
The actual transformation performed while executing a deploy.
Error while parsing a URef from a formatted string.
The result of ProtocolVersion::check_next_version.
Constants
The number of bytes in a serialized AccessRights.
The number of bytes in a Blake2b hash
The number of bytes in a serialized BlockTime.
The length of a deploy hash.
The maximum length for a dictionary_item_key.
The number of bytes in a Key::Dictionary.
The number of bytes in a Key::Hash.
The number of bytes in a serialized Phase.
Length of SemVer when serialized
The length of a transfer address.
The number of bytes in a URef address.
The number of bytes in a serialized URef where the AccessRights are not None.
Traits
Functions
Serializes the given data structure as a pretty-printed String of JSON using
serde_json::to_string_pretty(), but after first reducing any large hex-string values.
Returns the CLType describing a “named key” on the system, i.e. a (String, Key).
