Struct rustc_const_eval::transform::check_consts::ops::CellBorrow
source · pub struct CellBorrow;
Expand description
A borrow of a type that contains an UnsafeCell
somewhere. The borrow might escape to
the final value of the constant, and thus we cannot allow this (for now). We may allow
it in the future for static items.

Layout
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
