Struct rtic::RacyCell

#[repr(transparent)]
pub struct RacyCell<T>(_);

Internal replacement for static mut T

Used to represent RTIC Resources

Soundness:

1. Unsafe API for internal use only

2. 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 self.0.get() -> *mut T

3. 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 self.0.get() -> *mut T, demoted to *const T

Implementations
