preferences::PreferencesMap
[−]
[src]
type PreferencesMap<T = String> = HashMap<String, T>;
Generic key-value store for user data.
This is actually a wrapper type around std::collections::HashMap<String, T>
(with T
defaulting to String
), so use the HashMap
API methods to access and change user
data in memory.
To save or load user data, use the methods defined for
PreferencesTrait
, which will be automatically implemented for
PreferencesMap<T>
as long as T
is serializable. (See the
module documentation for examples and more details.)
