Trait lucet_runtime::Region

pub trait Region: RegionInternal {
    fn new_instance(
        &self, 
        module: Arc<dyn Module + 'static>
    ) -> Result<InstanceHandle, Error> { ... }
    fn new_instance_builder(
        &'a self, 
        module: Arc<dyn Module + 'static>
    ) -> InstanceBuilder<'a> { ... }
}

A memory region in which Lucet instances are created and run.

These methods return an InstanceHandle smart pointer rather than the Instance itself. This allows the region implementation complete control of where the instance metadata is stored.

Provided methods

fn new_instance(
    &self,
    module: Arc<dyn Module + 'static>
) -> Result<InstanceHandle, Error>

Create a new instance within the region.

Calling region.new_instance(module) is shorthand for region.new_instance_builder(module).build() for use when further customization is unnecessary.

Safety

This function runs the guest code for the WebAssembly start section, and running any guest code is potentially unsafe; see Instance::run().

fn new_instance_builder(
    &'a self,
    module: Arc<dyn Module + 'static>
) -> InstanceBuilder<'a>

Return an InstanceBuilder for the given module.
