Function syntax::codemap::original_sp

pub fn original_sp(sp: Span, enclosing_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?

Return the span itself if it doesn't come from a macro expansion, otherwise return the call site span up to the enclosing_sp by following the expn_info chain.
