Implementations§
source§impl Resources
impl Resources
sourcepub fn iter(&self) -> impl Iterator<Item = (ComponentId, &ResourceData)>
pub fn iter(&self) -> impl Iterator<Item = (ComponentId, &ResourceData)>
Iterate over all resources that have been initialized, i.e. given a ComponentId
sourcepub fn is_empty(&self) -> bool
pub fn is_empty(&self) -> bool
Returns true if there are no resources stored in the World
,
false otherwise.
sourcepub fn get(&self, component_id: ComponentId) -> Option<&ResourceData>
pub fn get(&self, component_id: ComponentId) -> Option<&ResourceData>
Gets read-only access to a resource, if it exists.
