pub type Key = String;Expand description
Denotes the type for elements that serve as keys in settings files.
This type is an alias for keys, e.g. the part of a line of a settings file
in front of the first =. Even though this is just an alias to String
for now, this provides better type safety and lets the compiler know what
you intend to do with a particular variable. This type is used in the
complex type Settings.
For an example how to use Key please refer to the example section of Settings.
