Used by hosts to limit resource consumption of instances. Identical to ResourceLimiter, except that the memory_growing and table_growing functions are async. Must be used with an async Store.

This trait is used with Store::limiter_async`: see those docs for restrictions on using other Wasmtime interfaces with an async resource limiter.

Required methods

fn memory_growing<'life0, 'async_trait>(
    &'life0 mut self,

    maximum: Option<usize>
) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait,
