[−][src]Struct substrate_wasmtime::HostRef
Represents a piece of data located in the host environment.
Methods
impl<T: 'static> HostRef<T>
[src]
pub fn new(item: T) -> HostRef<T>
[src]
Creates a new HostRef<T>
from T
.
pub fn borrow(&self) -> Ref<T>
[src]
pub fn borrow_mut(&self) -> RefMut<T>
[src]
pub fn ptr_eq(&self, other: &HostRef<T>) -> bool
[src]
Returns true if the two HostRef<T>
's point to the same value (not just
values that compare as equal).
pub fn anyref(&self) -> AnyRef
[src]
Returns an opaque reference to the wrapped data in the form of
an AnyRef
.
Panics
Panics if HostRef<T>
is already mutably borrowed.
