Struct sp_runtime_interface::wasm::ExchangeableFunction [−][src]
A function which implementation can be exchanged.
Internally this works by swapping function pointers.
Implementations
impl<T> ExchangeableFunction<T>[src]
impl<T: Copy> ExchangeableFunction<T>[src]
pub fn replace_implementation(
&'static self,
new_impl: T
) -> RestoreImplementation<T>[src]
&'static self,
new_impl: T
) -> RestoreImplementation<T>
Replace the implementation with new_impl.
Panics
Panics when trying to replace an already replaced implementation.
Returns
Returns the original implementation wrapped in RestoreImplementation.
pub fn get(&self) -> T[src]
Returns the internal function pointer.
