Module rustc_mir::borrow_check::nll::region_infer::annotation[][src]

🔬 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?

As part of the NLL unit tests, you can annotate a function with #[rustc_regions], and we will emit information about the region inference context and -- in particular -- the external constraints that this region imposes on others. The methods in this file handle the part about dumping the inference context internal state.
