Description

A AsciiString type backed by a ASCII encoded byte array and all the necessary functions to manipulate the string.

Synopsis

newtype AsciiString = AsciiString {
- toBytes :: UArray Char7
}
newtype MutableAsciiString st = MutableAsciiString (MUArray Char7 st)
fromBytesUnsafe :: UArray Word8 -> AsciiString
fromBytes :: UArray Word8 -> Maybe AsciiString

Binary conversion

fromBytesUnsafe :: UArray Word8 -> AsciiString Source #

Convert a Byte Array representing ASCII data directly to an AsciiString without checking for ASCII validity

If the input contains invalid Char7 value (anything above 0x7f), it will trigger runtime async errors when processing data.

In doubt, use fromBytes

fromBytes :: UArray Word8 -> Maybe AsciiString Source #

Convert a Byte Array representing ASCII checking validity.

If the byte array is not valid, then Nothing is returned
