Implementations§

source§

impl<'m, P: Clone> Preferences<'m, P>

source

pub fn new( default_prefs: P, accessors: &'m HashMap<String, Accessor<P, PrefValue>>, ) -> Self

Create a new Preferences object. The values provided in default_prefs are immutable and can always be restored using reset or reset_all.

source

pub fn values(&self) -> &RwLock<P>

Access to the data structure holding the preference values.

source

pub fn get(&self, key: &str) -> PrefValue

Retrieve a preference using its key

source

pub fn is_default(&self, key: &str) -> Result<bool, PrefError>

Has the preference been modified from its original value?

source

pub fn iter(&self) -> impl Iterator<Item = (String, PrefValue)> + '_

Creates an iterator over all keys and values

source

pub fn keys(&self) -> impl Iterator<Item = &str>

Creates an iterator over all keys

source

fn set_inner<V>( &self, key: &str, prefs: &mut P, val: V, ) -> Result<(), PrefError>
where V: Into<PrefValue>,

source

pub fn set<V>(&self, key: &str, val: V) -> Result<(), PrefError>
where V: Into<PrefValue>,

Set a new value for a preference, using its key.

source

pub fn set_all<M>(&self, values: M) -> Result<(), PrefError>
where M: IntoIterator<Item = (String, PrefValue)>,

source

pub fn reset(&self, key: &str) -> Result<PrefValue, PrefError>

source

pub fn reset_all(&self)
