how to draw 'inhibitory' arrow in latex tikz?

Question

i'm using this tikz-based library to draw nodes and arrows between them (https://github.com/jluttine/tikz-bayesnet). I want to draw an arrow that has a vertical line tip (|) (which usually means inhibition). How can this be done in tikz?

this is the code that draws a regular arrow from node "A" to node "B" that I want to replace with |:

\documentclass{article}  
\usepackage{tikz}
\usetikzlibrary{bayesnet}

\begin{document}

\begin{figure*}[!h]
\centering
\begin{tikzpicture}
  % Define nodes
  \node[const] (A) {$A$};
  \node[const, below=1cm of A] (B) {$B$};
  % connect them
  %%% how to make this an arrow with | tip?
  \edge{A}{B};
 \end{tikzpicture}
\caption{}
\end{figure*}
\end{document}

to compile you need the bayesnet package from the above link.

Do you want something like this?

\documentclass[tikz,border=10pt,multi]{standalone}
\usetikzlibrary{bayesnet,arrows.meta}
\begin{document}
\begin{tikzpicture}
  \node[const] (A) {$A$};
  \node[const, below=1cm of A] (B) {$B$};
  \edge [-Bar] {A}{B};
\end{tikzpicture}
\end{document}
