Struct rustc_mir::transform::check_consts::ops::CellBorrow[−][src]

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.
