#[repr(C)]pub struct Any { /* private fields */ }Expand description
Managed Any that can hold reference to values
Implementations§
Source§impl Any
impl Any
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,
Try to query if stored typed in Any exactly matches the type T
This function is fast in the case of failure and can be used to check if the type is compatible with T
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
Any::try_as<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 unsafe fn as_data_ptr(&mut self) -> *mut TVMFFIAny
pub unsafe fn into_raw_ffi_any(this: Self) -> TVMFFIAny
pub unsafe fn from_raw_ffi_any(data: TVMFFIAny) -> Self
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
