# `ShortText` type

data ShortText #

Compact representation of short `Strings`

The data is stored internally as UTF8 in an `ShortByteString` when compiled against `bytestring >= 0.10.4`, and otherwise the fallback is to use plain old non-compat '[Char]'.

Note: This type is for internal uses (such as e.g. `PackageName`) and shall not be exposed in Cabal's API

Since: Cabal-2.0.0.2

toShortText :: String -> ShortText #

Construct `ShortText` from `String`

fromShortText :: ShortText -> String #

Convert `ShortText` to `String`

# internal utilities

decodeStringUtf8 :: [Word8] -> String #

Decode `String` from UTF8-encoded octets.

Invalid data in the UTF8 stream (this includes code-points `U+D800` through `U+DFFF`) will be decoded as the replacement character (`U+FFFD`).

See also `encodeStringUtf8`

encodeStringUtf8 :: String -> [Word8] #

Encode `String` to a list of UTF8-encoded octets

Code-points in the `U+D800`-`U+DFFF` range will be encoded as the replacement character (i.e. `U+FFFD`).
