Crate eth_types

Ethereum and Evm types used to deserialize responses from web3 / geth.

Re-exports

• pub use keccak::keccak256;
• pub use keccak::Keccak;
• pub use bytecode::Bytecode;
• pub use error::Error;

Modules

• bytecode
  EVM byte code generator
• error
  Error module for the eth-types crate
• evm_types
  Evm types needed for parsing instruction sets as well
• geth_types
  Types needed for generating Ethereum traces
• keccak
  Plain keccak256 implementation
• macros
  Collection of utility macros used within this crate.
• sign_types
  secp256k1 signature types and helper functions.

Macros

• address
  Create an Address from a hex string. Panics on invalid input.
• bytecode
  EVM code macro
• evm_unimplemented
  Triggers a signal that a feature is unimplemented, panics if warn-unimplemented feature is not set
• word
  Create a Word from a hex string. Panics on invalid input.
• word_map
  Create a Word to Word HashMap from pairs of hex strings. Panics on invalid input.

Structs

• AccessList
  Access list
• AccessListItem
  Access list item
• Block
  The block type returned from RPC calls.
• Bytes
  Wrapper type around Bytes to deserialize/serialize “0x” prefixed ethereum hex strings
• DebugU256
  Little-endian large integer type 256-bit unsigned integer.
• EIP1186ProofResponse
  Struct used to define the result of eth_getProof call
• GethExecTrace
  The execution trace type returned by geth RPC debug_trace* methods. Corresponds to ExecutionResult in go-ethereum/internal/ethapi/api.go. The deserialization truncates the memory of each step in struct_logs to the memory size before the expansion, so that it corresponds to the memory before the step is executed.
• H64
• H160
  Fixed-size uninterpreted hash type with 20 bytes (160 bits) size.
• H256
  Fixed-size uninterpreted hash type with 32 bytes (256 bits) size.
• Signature
  An ECDSA signature
• StorageProof
  Struct used to define the storage proof
• Transaction
  Details of a signed transaction
• U64
  Little-endian large integer type Unsigned 64-bit integer.
• U256
  Little-endian large integer type 256-bit unsigned integer.
• U512
  Little-endian large integer type 512-bits unsigned integer.

Traits

• BigEndianHash
• Field
  Trait used to reduce verbosity with the declaration of the [PrimeField] trait and its repr.
• OpsIdentity
  trait to retrieve general operation itentity element
• ToAddress
  Trait used to convert a type to a Address.
• ToBigEndian
  Trait uset do convert a scalar value to a 32 byte array in big endian.
• ToLittleEndian
  Trait used to convert a scalar value to a 32 byte array in little endian.
• ToScalar
  Trait used to define types that can be converted to a 256 bit scalar value.
• ToWord
  Trait used to convert a type to a Word.

Type Aliases

• Address
• Hash
  Ethereum Hash (256 bits).
• Word
  Ethereum Word (256 bits).
