Struct rg3d_resource::Resource [−][src]
pub struct Resource<T: ResourceData, E: ResourceLoadError> { /* fields omitted */ }
Expand description
See module docs.
Implementations
Creates new resource with a given state.
Converts self to internal value.
Locks internal mutex provides access to the state.
Tries to lock internal mutex provides access to the state.
Allows you to obtain reference to the resource data.
Panic
An attempt to use method result will panic if resource is not loaded yet, or
there was load error. Usually this is ok because normally you’d chain this call
like this resource.await?.data_ref(). Every resource implements Future trait
and it returns Result, so if you’ll await future then you’ll get Result, so
call to data_ref will be fine.
