State Variables​

OFFSET_OR_LENGTH_MASK​

mask used for offsets and lengths to ensure no overflow

no sane abi encoding will pass in an offset or length greater than type(uint32).max (note that this does deviate from standard solidity behavior and offsets/lengths will be interpreted as mod type(uint32).max which will only impact malicious/buggy callers)

uint256 constant OFFSET_OR_LENGTH_MASK = 0xffffffff;

OFFSET_OR_LENGTH_MASK_AND_WORD_ALIGN​

uint256 constant OFFSET_OR_LENGTH_MASK_AND_WORD_ALIGN = 0xffffffe0;

SLICE_ERROR_SELECTOR​

equivalent to SliceOutOfBounds.selector, stored in least-significant bits

uint256 constant SLICE_ERROR_SELECTOR = 0x3b99b53d;
