:: String -> ByteString -package:spacecookie

O(n) Convert a String into a ByteString For applications with large numbers of string literals, pack can be a bottleneck.

Converts a Haskell string into a UTF8 encoded bytestring.

Encode String to UTF8-encoded ByteString Code-points in the U+D800-U+DFFF range will be encoded as the replacement character (i.e. U+FFFD).

Variant of toUTF8BS for lazy ByteStrings

Encode a String into a ByteString.

Encode String to ByteString using UTF-8.

Convert an UTF8-encoded String to a ByteString.

Parse a hexadecimal hash representation into its binary form suitable for encoding with printSHA256.

>>> packHex "48656c6c6f2c20776f726c642e"
"Hello, world."

Leading zeros can be omitted, i.e. it's unnecessary to pad the input to an even number of bytes:

>>> packHex "0"
"\NUL"

Convert hex strings to bytestrings, for example:

"3adf91c0" ==> B.pack [0x3a, 0xdf, 0x91, 0xc0]

Strings of odd length will cause an exception as will non-hex characters such as '0x'.

Converts the given String into a UTF-8 encoded ByteString.

Raises an error with a printf-specific prefix on the message string.

Deprecated: error appends the call stack now

Raises a SizeOverflowException, with a message using the given function name.

Synonym for error. Used for instances where the program has decided to exit because of invalid user input, or the user pressed quit etc. This function allows error to be reserved for programmer errors.
