Module testing 

Test factories for creating locations and spanned tokens succinctly.

The lexer and parser now require every token to carry a byte-span. These helpers keep tests concise while enforcing that requirement.

Functions

make_loc

Make a byte range location

mk_token

Make a single spanned token

mk_tokens

Make a vector of spanned tokens from a list of (Token, start, end)

mk_tokens_with_dummy_span

Create tokens with zero-length spans for convenience in tests that only care about token order.

Type Aliases

Tokens

Canonical alias for spanned tokens used across tests
