Struct rustc_const_eval::const_eval::MemoryExtra

pub struct MemoryExtra {
    pub(super) can_access_statics: bool,
}

Fields

can_access_statics: bool

We need to make sure consts never point to anything mutable, even recursively. That is relied on for pattern matching on consts with references. To achieve this, two pieces have to work together:

• Interning makes everything outside of statics immutable.
• Pointers to allocations inside of statics can never leak outside, to a non-static global. This boolean here controls the second part.

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.
