Creating Keys and unwrapping them

makeKey :: Text -> Either KeyError Key Source #

Create a new Key, checking its validity.

rawKey :: Key -> Text Source #

Convert a Key into its Text representation.

unsafeMakeKey :: Text -> Key Source #

Create a new Key without performing any checks.

Checking validity of raw text.

isValidKeyHead :: Char -> Bool Source #

Check if a character is suitable for use as the first character in a Key.

isValidKeyTail :: Char -> Bool Source #

Check if a character is suitable for use as any character except the first character in a Key.

Errors

data KeyError Source #

Errors returned when creating invalid keys.

Constructors

InvalidCharacterError InvalidCharacter

A character provided as a Key's name was invalid.

EmptyKeyError

A string of length 0 was provided as a Key's name.
