Struct sp_runtime_interface::wasm::ExchangeableFunction

source · [−]

pub struct ExchangeableFunction<T>(_);

Expand description

A function which implementation can be exchanged.

Internally this works by swapping function pointers.

Implementations

source

impl<T> ExchangeableFunction<T>

source

pub const fn new(impl_: T) -> Self

Create a new instance of ExchangeableFunction.

source

impl<T: Copy> ExchangeableFunction<T>

source

pub fn replace_implementation(
&'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.

source

pub fn get(&self) -> T

Returns the internal function pointer.
