[][src]Function syntax::std_inject::ignored_span

fn ignored_span(sp: Span) -> Span
🔬 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?

Craft a span that will be ignored by the stability lint's call to source_map's is_internal check. The expanded code uses the unstable #[prelude_import] attribute.
