Struct sp_wasm_interface::ExtendedHostFunctions
source · pub struct ExtendedHostFunctions<Base, Overlay> { /* private fields */ }Expand description
A wrapper which merges two sets of host functions, and allows the second set to override the host functions from the first set.
Trait Implementations§
source§impl<Base, Overlay> HostFunctions for ExtendedHostFunctions<Base, Overlay>where
Base: HostFunctions,
Overlay: HostFunctions,
impl<Base, Overlay> HostFunctions for ExtendedHostFunctions<Base, Overlay>where Base: HostFunctions, Overlay: HostFunctions,
source§fn host_functions() -> Vec<&'static dyn Function>
fn host_functions() -> Vec<&'static dyn Function>
Returns the host functions
Self provides.source§fn register_static<T>(registry: &mut T) -> Result<(), T::Error>where
T: HostFunctionRegistry,
fn register_static<T>(registry: &mut T) -> Result<(), T::Error>where T: HostFunctionRegistry,
Statically registers the host functions.
Auto Trait Implementations§

impl<Base, Overlay> Send for ExtendedHostFunctions<Base, Overlay>where Base: Send, Overlay: Send,

Blanket Implementations§

T: Any,

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