#[repr(C)]pub struct AnyView<'a> { /* private fields */ }Expand description
Unmanaged Any that can hold reference to values
Implementations§
Source§impl<'a> AnyView<'a>
impl<'a> AnyView<'a>
pub fn new() -> Self
pub fn type_index(&self) -> i32
Sourcepub fn try_as<T>(&self) -> Option<T>where
T: AnyCompatible,
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
Sourcepub fn debug_strong_count(&self) -> Option<usize>
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
