pub struct RacyCell<T>(_);

Expand description

Internal replacement for static mut T

Used to represent RTIC Resources

Soundness:

Unsafe API for internal use only
get_mut(&self) -> *mut T returns a raw mutable pointer to the inner T casting to &mut T is under control of RTIC RTIC ensures &mut T to be unique under Rust aliasing rules.

Implementation uses the underlying UnsafeCell<T> self.0.get() -> *mut T
get(&self) -> *const T returns a raw immutable (const) pointer to the inner T casting to &T is under control of RTIC RTIC ensures &T to be shared under Rust aliasing rules.

Implementation uses the underlying UnsafeCell<T> self.0.get() -> *mut T, demoted to *const T
