Enum ResourceKey 

pub enum ResourceKey {
    String(Rc<str>),
    Type(&'static TypeInfo),
    Object(Rc<dyn ResourceKeyObject>),
}

The key of a resource in a resource dictionary.

The object model this library mirrors uses arbitrary objects with value equality as keys. The keys used in practice are strings and types (a control theme is keyed by the type it targets), which get their own cheap variants; any other hashable value can be used through ResourceKey::object.

Variants

String(Rc<str>)

A string key.

Type(&'static TypeInfo)

A type key.

Object(Rc<dyn ResourceKeyObject>)

Any other key.

Implementations

impl ResourceKey

pub fn object<T: Eq + Hash + 'static>(value: T) -> Self

pub fn as_str(&self) -> Option<&str>
