Bytes

Bytes operations.

Functions

indexOf

Forward search for s in buffer If s is present in the buffer, returns the index of the first instance If s is not present in the buffer, returns type(uint256).max NOTE: replicates the behavior of https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/indexOf[Javascript's Array.indexOf]

function indexOf(bytes memory buffer, bytes1 s) internal pure returns (uint256);

indexOf

Forward search for s in buffer starting at position pos If s is present in the buffer (at or after pos), returns the index of the next instance If s is not present in the buffer (at or after pos), returns type(uint256).max NOTE: replicates the behavior of https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/indexOf[Javascript's Array.indexOf]

function indexOf(bytes memory buffer, bytes1 s, uint256 pos) internal pure returns (uint256);

lastIndexOf

Backward search for s in buffer If s is present in the buffer, returns the index of the last instance If s is not present in the buffer, returns type(uint256).max NOTE: replicates the behavior of https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/lastIndexOf[Javascript's Array.lastIndexOf]

function lastIndexOf(bytes memory buffer, bytes1 s) internal pure returns (uint256);

lastIndexOf

Backward search for s in buffer starting at position pos If s is present in the buffer (at or before pos), returns the index of the previous instance If s is not present in the buffer (at or before pos), returns type(uint256).max NOTE: replicates the behavior of https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/lastIndexOf[Javascript's Array.lastIndexOf]

function lastIndexOf(bytes memory buffer, bytes1 s, uint256 pos) internal pure returns (uint256);

slice

Copies the content of buffer, from start (included) to the end of buffer into a new bytes object in memory. NOTE: replicates the behavior of https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/slice[Javascript's Array.slice]

function slice(bytes memory buffer, uint256 start) internal pure returns (bytes memory);

slice

Copies the content of buffer, from start (included) to end (excluded) into a new bytes object in memory. NOTE: replicates the behavior of https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/slice[Javascript's Array.slice]

function slice(bytes memory buffer, uint256 start, uint256 end) internal pure returns (bytes memory);

_unsafeReadBytesOffset

Reads a bytes32 from a bytes array without bounds checking. NOTE: making this function internal would mean it could be used with memory unsafe offset, and marking the assembly block as such would prevent some optimizations.

function _unsafeReadBytesOffset(bytes memory buffer, uint256 offset) private pure returns (bytes32 value);
