A ShMem is an interface to shared maps. They are the backbone of crate::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

fn as_ptr_of<T: Sized>(&self) -> Option<*const T>

Convert to a ptr of a given type, checking the size. If the map is too small, returns None

fn as_mut_ptr_of<T: Sized>(&mut self) -> Option<*mut T>

Convert to a mut ptr of a given type, checking the size. If the map is too small, returns None

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
