| Description |
| An efficient implementation of strings.

|
| Synopsis |
|
|
|
|
| The PackedString type |
|
| data PackedString |
| A space-efficient representation of a String, which supports various
efficient operations. A PackedString contains full Unicode Chars. | | Instances | |
|
|
| Converting to and from PackedStrings |
|
| packString :: String -> PackedString |
| Convert a String into a PackedString |
|
| unpackPS :: PackedString -> String |
| Convert a PackedString into a String |
|
| I/O with PackedStrings |
|
| hPutPS :: Handle -> PackedString -> IO () |
Outputs a PackedString to the specified Handle. NOTE: the representation of the PackedString in the file is assumed to
be in the ISO-8859-1 encoding. In other words, only the least signficant
byte is taken from each character in the PackedString. |
|
| hGetPS :: Handle -> Int -> IO PackedString |
Read a PackedString directly from the specified Handle. This
is far more efficient than reading the characters into a String
and then using packString. NOTE: as with hPutPS, the string representation in the file is
assumed to be ISO-8859-1. |
