Functions

parseOperand

function parseOperand(ParseState memory state, uint256 cursor, uint256 end) internal pure returns (uint256);

Standard dispatch for handling an operand after it is parsed, using the encoded function pointers on the current parse state. Requires that the word index has been looked up by the parser, exists, and the literal values have all been parsed out of the operand string. In the case of the main parser this will all be done inline, but in the case of a sub parser the literal extraction will be done first, then the word lookup will have to be done by the sub parser, alongside the values provided by the main parser.

function handleOperand(ParseState memory state, uint256 wordIndex) internal pure returns (Operand);

handleOperandDisallowed

function handleOperandDisallowed(uint256[] memory values) internal pure returns (Operand);

handleOperandSingleFull

There must be one or zero values. The fallback is 0 if nothing is provided, else the provided value MUST fit in two bytes and is used as is.

function handleOperandSingleFull(uint256[] memory values) internal pure returns (Operand operand);

handleOperandDoublePerByteNoDefault

There must be exactly two values. There is no default fallback. Each value MUST fit in one byte and is used as is.

function handleOperandDoublePerByteNoDefault(uint256[] memory values) internal pure returns (Operand operand);

handleOperand8M1M1

8 bit value then maybe 1 bit flag then maybe 1 bit flag. Fallback to 0 for both flags if not provided.

function handleOperand8M1M1(uint256[] memory values) internal pure returns (Operand operand);

handleOperandM1M1

2x maybe 1 bit flags. Fallback to 0 for both flags if not provided.

function handleOperandM1M1(uint256[] memory values) internal pure returns (Operand operand);
