Struct dync::CopyValueRef

pub struct CopyValueRef<'a> { /* fields omitted */ }

A generic value reference to a Copy type.

Methods

impl<'a> CopyValueRef<'a>

pub fn size(&self) -> usize

Get the size of the value pointed-to by this reference.

pub fn value_type_id(&self) -> TypeId

Get the TypeId of the referenced value.

pub fn is<T: 'static>(&self) -> bool

Returns true if this referenced value's type is the same as T.

pub fn new<T: Elem>(typed: &'a T) -> CopyValueRef<'a>

Create a new CopyValueRef from a typed reference.

pub fn downcast<T: Elem>(self) -> Option<&'a T>

Downcast this value reference into a borrowed T type. Return None if the downcast fails.
