Struct rustc::mir::interpret::Pointer

pub struct Pointer { /* fields omitted */ }

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

A wrapper type around PrimVal that cannot be turned back into a PrimVal accidentally. This type clears up a few APIs where having a PrimVal argument for something that is potentially an integer pointer or a pointer to an allocation was unclear.

I (@oli-obk) believe it is less easy to mix up generic primvals and primvals that are just the representation of pointers. Also all the sites that convert between primvals and pointers are explicit now (and rare!)
