Methods

impl AnyRef

pub fn new(data: Box<dyn Any>) -> Self

Creates a new instance of AnyRef from Box<dyn Any>.

pub fn null() -> Self

Creates a Null reference.

pub fn data(&self) -> Ref<Box<dyn Any>>

Returns the data stored in the reference if available.

Panics

Panics if the variant isn't AnyRef::Other.

pub fn ptr_eq(&self, other: &AnyRef) -> bool

Returns true if the two AnyRef<T>'s point to the same value (not just values that compare as equal).

pub fn host_info(&self) -> Option<RefMut<Box<dyn Any>>>

Returns a mutable reference to the host information if available.

Panics

Panics if AnyRef is already borrowed or AnyRef is Null.

pub fn set_host_info(&self, info: Option<Box<dyn Any>>)

Sets the host information for an AnyRef.

Panics

Panics if AnyRef is already borrowed or AnyRef is Null.
