name: String,
module: Module
) -> Result<Self, Error<E>>[src]
program: Weak<ProgramInstanceEssence<E>>,
name: String,
module: Module
) -> Result<Self, Error<E>>
Instantiate given module within program context.
fn instantiate<'a>(
&mut self,
externals: Option<&'a HashMap<String, Arc<ModuleInstanceInterface<E> + 'a>>>
) -> Result<(), Error<E>>[src]
&mut self,
