pub struct NonGenericTypeCell<T>(/* private fields */)
where
T: TypedProperty;Expand description
A container for TypeInfo over non-generic types, allowing instances to be stored statically.
This is specifically meant for use with non-generic types. If your type is generic,
then use GenericTypeCell instead. Otherwise, it will not take into account all
monomorphizations of your type.
Non-generic TypePaths should be trivially generated with string literals and concat!.
§Example
use bevy_reflect::utility::NonGenericTypeInfoCell;
struct Foo {
bar: i32
}
impl Typed for Foo {
fn type_info() -> &'static TypeInfo {
static CELL: NonGenericTypeInfoCell = NonGenericTypeInfoCell::new();
CELL.get_or_set(|| {
let fields = [NamedField::new::<i32>("bar")];
let info = StructInfo::new::<Self>(&fields);
TypeInfo::Struct(info)
})
}

T: TypedProperty,
impl<T> NonGenericTypeCell<T>where
T: TypedProperty,
Sourcepub const fn new() -> NonGenericTypeCell<T>
pub const fn new() -> NonGenericTypeCell<T>
Initialize a NonGenericTypeCell for non-generic types.
Sourcepub fn get_or_set<F>(&self, f: F) -> &<T as TypedProperty>::Stored
pub fn get_or_set<F>(&self, f: F) -> &<T as TypedProperty>::Stored
Returns a reference to the TypedProperty stored in the cell.
If there is no entry found, a new one will be generated from the given function.
