Struct Runtime

pub struct Runtime<'module, 'source, I: Importer> { /* private fields */ }

Implementations

impl<'m, 's, I: Importer> Runtime<'m, 's, I>

pub fn instantiate(module: &'m Module<'s>, importer: I) -> Result<Self>

Initialize states of execution (stack, memory, …) and instantiate a given module. It means that ‘start function’ is invoked in this function if presents. The module is assumed to be validated. If an invalid module is given, the behavior is unspecified, meaning that it may crash or the result may be incorrect.
