Constant syntax_pos::DUMMY_SP

pub const DUMMY_SP: Span = Span(0)

🔬 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?

Dummy span, both position and length are zero, syntax context is zero as well. This span is kept inline and encoded with format 0.
