Struct regex_automata::util::determinize::state::StateBuilderEmpty

pub(crate) struct StateBuilderEmpty(Vec<u8>);

A state builder that represents an empty state.

This is a useful “initial condition” for state construction. It has no NFA state IDs, no assertions set and no pattern IDs. No allocations are made when new() is called. Its main use is for being converted into a builder that can capture assertions and pattern IDs.
