Static libslide::common::DUMMY_SP

pub(crate) static  DUMMY_SP: Span

A dummy span for use in places where a span is not (yet) known.

Clearly this span is incorrect since lo = 10001 > 1 = hi, but a well-formed span must observe the invariant lo <= hi.

NB: This is only to be used during migration, refactoring, or where a span is not later consumed. Do not use this for interned expressions exposed to users.
