pub fn strip_complement(schema: &mut Schema)Expand description
Strip byte-position constraints from a schema.
Removes start-byte, end-byte, and interstitial-* constraints
— the byte-positional portion of the layout fibre that
emit_pretty cannot reconstruct (the parser invents fresh
positions). chose-alt-* discriminators are preserved because
they’re the categorical witness of which CHOICE alternative the
parser took and emit_pretty consumes them directly to dispatch
without re-deriving the choice. This is the EmitParse law’s
“complement” projection — distinct from
Schema::forget_layout, which strips every layout-fibre sort
including chose-alt-* to produce a truly abstract schema for
the parse/decorate/emit lens.
