A ShMem is an interface to shared maps. They are the backbone of crate::bolts::llmp for inter-process communication. All you need for scaling on a new target is to implement this interface, as well as the respective ShMemProvider.

Required Methods

fn id(&self) -> ShMemId

Get the id of this shared memory mapping

fn len(&self) -> usize

Get the size of this mapping

Provided Methods

fn is_empty(&self) -> bool

Check if the mapping is empty

unsafe fn as_object<T: Sized + 'static>(&self) -> &T

Convert to an owned object reference

Safety

This function is not safe as the object may be not initialized. The user is responsible to initialize the object with something like *shmem.as_object_mut::<T>() = T::new();

unsafe fn as_object_mut<T: Sized + 'static>(&mut self) -> &mut T

Convert to an owned object mutable reference

Safety

This function is not safe as the object may be not initialized. The user is responsible to initialize the object with something like *shmem.as_object_mut::<T>() = T::new();

fn description(&self) -> ShMemDescription

Get the description of the shared memory mapping

fn write_to_env(&self, env_name: &str) -> Result<(), Error>

Write this map’s config to env
