Description

What it does

As per title, for projects with MSRV 1.82 or higher:

  • Suggest replacing addr_of!(x) with &raw const x
  • Suggest replacing addr_of_mut!(x) with &raw mut x
Advantage

The macros are documented as soft-deprecated; seems like encouraging use of the operators would fit that recommendation.

Drawbacks

No response

Example
addr_of!(x);
addr_of_mut!(y);

Could be written as:

&raw const x;
&raw mut y;
