Package abi implements the Ethereum ABI (Application Binary Interface).

Package hexutil implements hex encoding with 0x prefix.

Package math provides integer math utilities.

Package rlp implements the RLP serialization format.

BigToAddress returns Address with byte values of b.

BigToHash sets byte representation of b to hash.

Bytes2Hex returns the hexadecimal encoding of d.

BytesToAddress returns Address with value b.

BytesToHash sets b to hash.

Join the slice array of the parameter to return a slice.

CopyBytes returns an exact copy of the provided bytes.

CreateAddress creates an ethereum address given the bytes and the nonce.

Hash calculation after serializing objects.

Call the HashObject method and turn the result into a hash object.

FromHex returns the bytes represented by the hexadecimal string s.

hasHexPrefix validates str begins with '0x' or '0X'.

If the object implements common.Hasher Interface, the HashValue() method is directly used to generate the hash value.

Hex2Bytes returns the bytes represented by the hexadecimal string str.

Hex2BytesFixed returns bytes of a specified fixed length flen.

HexToAddress returns Address with byte values of s.

HexToHash sets byte representation of s to hash.

IsHex validates whether each byte is valid hexadecimal string.

IsHexAddress verifies whether a string can represent a valid hex-encoded Ethereum address or not.

isHexCharacter returns bool of c being a valid hexadecimal.

LeftPadBytes zero-pads slice to the left up to length l.

depth: If it is a positive number, it is the depth of the specified merkle tree.

MerkleHash Calculate merkle tree root hash with hashlist parameter according to fixed algorithm.

When sorting a pointer type object slice, the Less method needs to be written.

RightPadBytes zero-pads slice to the right up to length l.

let b0.bit(0~7) and b1.bit(0~7) be bit(0~15), and returns bit(shifts, shifts+length) 0 <= shifts <= 7; 1<= length <= 8 default:8 ShiftBytes(0xf0, 0xf, 3, 7) would be 0x7e ShiftBytes(0xf0, 0xf, 3) would be 0xfe.

Divide bs into slices according to size, and each slice length is size.

String to ElectionType, invalid string bool returns false.

cut bytes from bs, bits [from, to).

Since 16 bit counting is used in serialization, the maximum supported proof height cannot exceed 65535.

Interface type that can calculate hash values.

GasPool tracks the amount of gas available during execution of the transactions in a block.
