where UserData: 'static,

Defines a new untyped handler for external calls with a given symbol.

pub fn define_typed<Params, Args>( &mut self, symbol: impl AsRef<[u8]>, func: impl IntoCallFn<UserData, UserError, Params, Args>, ) -> Result<&mut Self, Error>

Defines a new statically typed handler for external calls with a given symbol.

pub fn instantiate_pre( &self, module: &Module, ) -> Result<InstancePre<UserData, UserError>, Error>
