I know I could easily do a checked cast and unwrap it, but that feels a bit silly because of how certain I am that the check can never fail. In idiomatic rust, is this bad practice? Should unsafe be unconditionally avoided unless the needed performance can't be achieved without it, or are there exceptions (possibly like this) where it's okay?

Any help will b appreciated.\n\nUPDATE: Ok so there where a few formatting errors in my code which i solved. Now when I run the code, the terminal goes unresponsive." ]

I want to insert tikzpictures into my book, and even though they render perfectly when using render_book(\"index.Rmd\", \"pdf_book\"), they do not appear at all, on any browser (I've tried Chrome, Firefox, and even Internet Explorer) when I use render_book(\"index.Rmd\", \"gitbook\"). Likewise when using preview_chapter instead of render_book.\n\nHere is the code that can be used to render my Tikz image:\n\n\\def\\firstcircle{(0:-0.5cm) circle (1.5cm)}\n\\def\\secondcircle{(0:0.4cm) circle (0.5cm)}\n\n\\colorlet{circle edge}{blue!50}\n\\colorlet{circle area}{blue!20}\n\n\\tikzset{filled/.style={fill=circle area, draw=circle edge, thick},\n outline/.style={draw=circle edge, thick}}\n\n\\begin{figure}\n\\centering\n\\begin{tikzpicture}\n \\begin{scope}\n \\clip \\firstcircle;\n \\secondcircle;\n \\end{scope}\n \\draw[outline] \\firstcircle node {$B$};\n \\draw[outline] \\secondcircle node {$A$};\n\\end{tikzpicture}\n\\caption{$A$ as a subset of $B$}\n\\end{figure}\n\n\nWhen I use pdf_book it's beautiful. If I use gitbook it just does not appear. I've tried to do something similar as what's described in this question here i.e. using the same chunk but replacing that code with my code (though I did center mine) like so:\n\n```{r, echo=FALSE, engine='tikz', out.width='90%', fig.ext='pdf', fig.align='center', fig.cap='Some caption.'}\n\\def\\firstcircle{(0:-0.5cm) circle (1.5cm)}\n\\def\\secondcircle{(0:0.4cm) circle (0.5cm)}\n\n\\colorlet{circle edge}{blue!50}\n\\colorlet{circle area}{blue!20}\n\n\\tikzset{filled/.style={fill=circle area, draw=circle edge, thick},\n outline/.style={draw=circle edge, thick}}\n\n\\begin{tikzpicture}\n \\begin{scope}\n \\clip \\firstcircle;\n \\secondcircle;\n \\end{scope}\n \\draw[outline] \\firstcircle node {$B$};\n \\draw[outline] \\secondcircle node {$A$};\n\\end{tikzpicture}\n```\n\n\nwhen I do this, again it renders beautifully in pdfbook and actually I get further in gitbook (the figure caption appears and a \"broken image link\" symbol appears, I've tried across browsers, as mentioned) but still no image.\n\nAny ideas on how I can get this to work?" ]
