Doesn't build

Hi. Thanks a lot for this package. It doesn't build. Here are steps to reproduce (Dockerfile):

FROM debian:bullseye
ENV LC_ALL C.UTF-8
RUN apt-get update && apt-get install -y apt-utils gcc curl less nano mc whiptail locales man-db wget procps sudo
RUN printf '%s\n' 'PS1='\''\[\033[1;31m\]\w\$\[\033[0m\] '\''' > ~/.bashrc
RUN curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | bash -s -- -y --default-toolchain none
RUN . "$HOME/.cargo/env"; rustup toolchain install stable --allow-downgrade
RUN . "$HOME/.cargo/env"; cd /root && cargo new a && cd a && echo 'rustomaton="0.2.1"' >> Cargo.toml && cargo build

Output: https://paste.debian.net/1205994/

Also, if you think that your package should not be used in practice, and I should pick something else instead, please, tell me this. I need some library to compute intersections of regular languages and compare regular languages for equality
