Struct wasmer_vm::VMExternRef [−][src]
#[repr(transparent)]pub struct VMExternRef(_);
Expand description
This type does not do reference counting automatically, reference counting can be done with
Self::ref_clone
and Self::ref_drop
.
Implementations
impl VMExternRef
[src]
impl VMExternRef
[src]pub const fn null() -> VMExternRef
[src]
pub const fn null() -> VMExternRef
[src]New null extern ref
pub fn new<T>(value: T) -> VMExternRef where
T: Any + Send + Sync + 'static,
[src]
pub fn new<T>(value: T) -> VMExternRef where
T: Any + Send + Sync + 'static,
[src]Make a new extern reference
pub fn downcast<T>(&self) -> Option<&T> where
T: Any + Send + Sync + 'static,
[src]
pub fn downcast<T>(&self) -> Option<&T> where
T: Any + Send + Sync + 'static,
[src]Try to downcast to the given value
pub fn ref_inc_by(&self, val: usize)
[src]
pub fn ref_inc_by(&self, val: usize)
[src]A low-level function to increment the strong-count a given number of times.
This is used as an optimization when implementing some low-level VM primitives.
If you’re using this type directly for whatever reason, you probably want
Self::ref_clone
instead.
pub fn ref_clone(&self) -> VMExternRef
[src]
pub fn ref_clone(&self) -> VMExternRef
[src]A deep copy of the reference, increments the strong count.
