Struct sc_executor_common::runtime_blob::ExposedMutableGlobalsSet

source · 
pub struct ExposedMutableGlobalsSet(_);
Expand description

A set of exposed mutable globals.

This is set of globals required to create a GlobalsSnapshot and that are collected from a runtime blob that was instrumented by RuntimeBlob::expose_mutable_globals. If the code wasn’t instrumented then it would be empty and snapshot would do nothing.

Implementations§

source§

impl ExposedMutableGlobalsSet

source

pub fn collect(runtime_blob: &RuntimeBlob) -> Self

Collect the set from the given runtime blob. See the struct documentation for details.

impl<T> Downcast for Twhere T: Any,

§

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

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 + 'static>

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 Twhere T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send + 'static>

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