pub fn function<H: GuestFunctionHandle + 'static>(&self) -> Option<&H::Callback>

Looks up cached guest export by function handle.

pub fn function_or_cache<H: GuestFunctionHandle + 'static>( &mut self, ) -> Option<&H::Callback>

Looks up cached guest export by function handle. If no matches are found tries to resolve export from wasm instance and cache the result.

pub fn function_unwrap<H: GuestFunctionHandle + 'static>(&self) -> &H::Callback

Looks up cached guest export by function handle.

Panics

If function was not cached with make_exports!.

pub fn function_unwrap_or_cache<'this: 'cb, 'cb, H: GuestFunctionHandle + 'static>( &'this mut self, ) -> &'cb H::Callback

Looks up cached guest export by function handle. If no matches are found tries to resolve export from wasm instance and cache the result.
