Struct ModuleInstance

pub struct ModuleInstance { /* private fields */ }

Module instance.

Implementations

impl ModuleInstance

pub fn new<'a>( program: Weak<ProgramInstanceEssence>, name: String, module: Module, ) -> Result<Self, Error>

Instantiate given module within program context.

pub fn instantiate<'a>( &mut self, externals: Option<&'a HashMap<String, Arc<dyn ModuleInstanceInterface + 'a>>>, ) -> Result<(), Error>

Run instantiation-time procedures (validation). Module is not completely validated until this call.

pub fn run_start_function(&self) -> Result<(), Error>

Run start function [if any].
