Functions

function encodeAddress(address _val)
  internal
  pure
  returns (bytes memory encoded);

function encodeUint256(uint256 _val)
  internal
  pure
  returns (bytes memory encoded);

Encodes the size of bytes in RLP format.

function encodeNonSingleBytesLen(uint64 _len)
  internal
  pure
  returns (bytes memory);

Parameters

Name	Type	Description
`_len`	`uint64`	The length of the bytes to encode. It has a `uint64` type since as larger values are not supported. NOTE: panics if the length is 1 since the length encoding is ambiguous in this case.

Encodes the size of list items in RLP format.

function encodeListLen(uint64 _len) internal pure returns (bytes memory);

Parameters

Name	Type	Description
`_len`	`uint64`	The length of the bytes to encode. It has a `uint64` type since as larger values are not supported.

function _encodeLength(uint64 _len, uint256 _offset)
  private
  pure
  returns (bytes memory encoded);

Computes the index of the highest byte set in number.

Uses little endian ordering (The least significant byte has index 0). NOTE: returns 0 for 0

function _highestByteSet(uint256 _number) private pure returns (uint256 hbs);
