Struct scrypto_test::prelude::FakeWasmiInstanceEnv

source · 
pub struct FakeWasmiInstanceEnv {
    runtime_ptr: MaybeUninit<*mut Box<dyn WasmRuntime>>,
}
Expand description

This is to construct a stub Store<FakeWasmiInstanceEnv>, which is a part of WasmiModule struct and serves as a placeholder for the real Store<WasmiInstanceEnv>. The real store is set (prior being transumted) when the WasmiModule is being instantiated. In fact the only difference between a stub and real Store is the Send + Sync manually implemented for the former one, which is required by WasmiModule cache (for std configuration) but shall not be implemented for the latter one to prevent sharing it between the threads since pointer might point to volatile data.

impl<T> Any for T
where T: 'static + ?Sized,

source§

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more
§

impl<U> As for U

§

fn as_<T>(self) -> T
where T: CastFrom<U>,

Casts self to type T. The semantics of numeric casting with the as operator are followed, so <T as As>::as_::<U> can be used in the same way as T as U for numeric conversions. Read more

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
§

impl<T> DowncastSync for T
where T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
