#[non_exhaustive]pub struct Type {

type_info)Expand description
Compile-time type information.
Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional
Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.kind: TypeKind🔬This is a nightly-only experimental API. (
type_info)Per-type information

🔬This is a nightly-only experimental API. (type_info)
pub const fn of<T>() -> Typewhere
T: ?Sized,
type_info)Returns the type information of the generic type parameter.
Note: Unlike TypeIds obtained via TypeId::of, the Type
struct and its fields contain TypeIds that are not necessarily
derived from types that outlive 'static. This means that using
the TypeIds (transitively) obtained from this function will
be able to break invariants that other TypeId consuming crates
may have assumed to hold.

then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.Source§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot

Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.
