Struct texlang::vm::UnexpandedStream

pub struct UnexpandedStream<S>(/* private fields */);

Stream that returns input tokens without performing expansion.

The unexpanded stream is used when reading tokens without performing expansion; e.g., when reading the replacement text for a macro defined using \def.

It be obtained from either the ExecutionInput or the ExpansionInput using the ExpandedStream trait methods.
