Implementations§

source§

impl<K: Hash + Eq> PropertyStore<K>

source

pub fn new() -> Self

Create an empty property store.

source

pub fn insert<V: Into<PropertyValue>>( &mut self, key: K, value: V ) -> Option<PropertyValue>

Insert a property. Returns the old property value if there was already a property stored under this key.

source

pub fn get<Q>(&self, key: &Q) -> Option<&PropertyValue>where K: Borrow<Q>, Q: Eq + Hash + ?Sized,

Get a property value by the property key.

source

pub fn contains_key<Q>(&self, key: &Q) -> boolwhere K: Borrow<Q>, Q: Eq + Hash + ?Sized,

Check if the key is contained in this property store.

source

pub fn get_string<Q>(&self, key: &Q) -> Option<&RcString>where K: Borrow<Q>, Q: Eq + Hash + ?Sized,

Get a string property value by key. If the property value is not a string None is returned.
