LibParse

Functions

Parses a word that matches a tail mask between cursor and end. The caller has several responsibilities while safely using this word.

The caller MUST ensure that the word is not zero length. I.e. end - cursor > 0.
The caller MUST ensure the head of the word (the first character) is valid according to some head mask. Generally it is expected that the valid chars for a head and tail may be different. This function will extract every other character from the word, starting with the second character, and check that it is valid according to the tail mask. If any invalid characters are found, the parsing will stop looping as it is assumed the remaining data is valid as something else, just not a word.

function parseWord(uint256 cursor, uint256 end, uint256 mask) internal pure returns (uint256, bytes32);

Skip an unlimited number of chars until we find one that is not in the mask.

function skipMask(uint256 cursor, uint256 end, uint256 mask) internal pure returns (uint256);

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

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

function parse(ParseState memory state) internal pure returns (bytes memory bytecode, uint256[] memory);
