Inside a metadata node, and before any Lazy or LazySeq. The position is that of the node itself.

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?

Inside a metadata node, with a previous Lazy or LazySeq. The position is a conservative estimate of where that previous Lazy / LazySeq would end (see their comments).
