Struct rustc_mir::borrow_check::nll::region_infer::values::PlaceholderIndex

pub struct PlaceholderIndex(u32);

🔬 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?
