Struct AnyView

#[repr(C)]
pub struct AnyView<'a> { /* private fields */ }

Unmanaged Any that can hold reference to values

Implementations

impl<'a> AnyView<'a>

pub fn new() -> Self

pub fn type_index(&self) -> i32

pub fn downcast_ref<T: ObjectCore>(&self) -> Option<&T>

Borrow the viewed object as T when its runtime type is T or a subtype.

T is an object representation type such as MyPairObj. Non-object values and unrelated object types return None. This does not change the object’s reference count; the borrow cannot outlive this view or the owner it borrows. See Any::downcast_ref for an example.

pub fn try_as<T>(&self) -> Option<T>

where T: AnyCompatible,

More strict version than try_from/try_into

This function will not try to cast the type and ensures invariance that the return value is only Some(T) Any::from(T) contains exactly the same value value

will return Some(T) if the type is exactly compatible with T will return None if the type is not compatible with T

pub fn debug_strong_count(&self) -> Option<usize>

Get the strong count of the underlying object for testing/debugging purposes

If the underlying object is not ref counted, return None
