Struct kernel::utilities::StaticRef

pub struct StaticRef<T> { /* private fields */ }

A pointer to statically allocated mutable data such as memory mapped I/O registers.

This is a simple wrapper around a raw pointer that encapsulates an unsafe dereference in a safe manner. It serve the role of creating a &'static T given a raw address and acts similarly to extern definitions, except StaticRef is subject to module and crate boundaries, while extern definitions can be imported anywhere.

Implementations

impl<T> StaticRef<T>

pub const unsafe fn new(ptr: *const T) -> StaticRef<T>

Create a new StaticRef from a raw pointer

Safety

Callers must pass in a reference to statically allocated memory which does not overlap with other values.
