pub type PreferencesMap<T = String> = HashMap<String, T>;Expand description
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 the trait
Preferences, which will be automatically implemented for
PreferencesMap<T> as long as T is serializable. (See the
module documentation for examples and more details.)
