Enums

• ConversionError
• ParseUnits
  This enum holds the numeric types that a possible to be returned by parse_units and that are taken by format_units.
• Units
  Common Ethereum unit types.

Constants

• EIP1559_FEE_ESTIMATION_DEFAULT_PRIORITY_FEE
  The default max priority fee per gas, used in case the base fee is within a threshold.
• EIP1559_FEE_ESTIMATION_PAST_BLOCKS
  The number of blocks from the past for which the fee rewards are fetched for fee estimation.
• EIP1559_FEE_ESTIMATION_PRIORITY_FEE_TRIGGER
  The threshold for base fee below which we use the default priority fee, and beyond which we estimate an appropriate value for priority fee.
• EIP1559_FEE_ESTIMATION_REWARD_PERCENTILE
  The default percentile of gas premiums that are fetched for fee estimation.
• EIP1559_FEE_ESTIMATION_THRESHOLD_MAX_CHANGE
  The threshold max change/difference (in %) at which we will ignore the fee history values under it.
• WEI_IN_ETHER
  1 Ether = 1e18 Wei == 0x0de0b6b3a7640000 Wei

Functions

• eip1559_default_estimator
  The default EIP-1559 fee estimator which is based on the work by MyCrypto
• format_bytes32_string
  Returns a bytes32 string representation of text. If the length of text exceeds 32 bytes, an error is returned.
• format_ether
  Format the output for the user which prefer to see values in ether (instead of wei)
• format_units
  Divides the provided amount with 10^{units} provided.
• from_bytes_to_h256
  Converts a Bytes value into a H256, accepting inputs that are less than 32 bytes long. These inputs will be left padded with zeros.
• from_unformatted_hex_map
  Deserializes the input into an Option<HashMap<H256, H256>>, using from_unformatted_hex to deserialize the keys and values.
• get_contract_address
  The address for an Ethereum contract is deterministically computed from the address of its creator (sender) and how many transactions the creator has sent (nonce). The sender and nonce are RLP encoded and then hashed with Keccak-256.
• get_create2_address
  Returns the CREATE2 address of a smart contract as specified in EIP1014
• get_create2_address_from_hash
  Returns the CREATE2 address of a smart contract as specified in EIP1014, taking the pre-computed hash of the init code as input.
• hash_message
  Hash a message according to EIP-191 (version 0x01).
• id
  Calculate the function selector as per the contract ABI specification. This is defined as the first 4 bytes of the Keccak256 hash of the function signature.
• keccak256
  Compute the Keccak-256 hash of input bytes.
• parse_bytes32_string
  Returns the decoded string represented by the bytes32 encoded data.
• parse_checksummed
  Parses an EIP-1191 checksum address.
• parse_ether
  Converts the input to a U256 and converts from Ether to Wei.
• parse_units
  Multiplies the provided amount with 10^{units} provided.
• public_key_to_address
  Converts an public key, in compressed or uncompressed form to an Ethereum address
• raw_public_key_to_address
  Convert a raw, uncompressed public key to an address.
• secret_key_to_address
  Converts a K256 SigningKey to an Ethereum Address
• serialize
  Serialize a type.
• to_checksum
  Encodes an Ethereum address to its EIP-55 checksum.
