I would like to render a commutative diagram involving some topological immersions; these are referred to elsewhere using Glooparrowright B with the arrow coming from amsmath.

I've had a heck of a time attempting to search for how to do this, as all my search results produce answers to the question "how do I get an arrow from a node to itself".

The M'W'E with the arrow I'd like to replace with looparrowright labelled loop

documentclass{standalone}

usepackage{tikz-cd}

begin{document}

  begin{tikzcd}

    A ar[r]        & B \

    G ar[u, hook]

      ar[ur, loop] & \

      % this arrow^ does not have the loop tail

      % instead produces an arrow from G to G.

  end{tikzcd}

end{document}

I'm guessing something custom could be done with the decorations library but I don't know how to do that.

Welcome to TeX-SE! Getting these arrows in is discussed in the tikz-cd manual at the very end, i.e. on p. 15.

documentclass{standalone}

usepackage{amsmath,amssymb}

usepackage{tikz-cd}

tikzset{% from the manual

math to/.tip={Glyph[glyph math command=rightarrow]},

loop/.tip={Glyph[glyph math command=looparrowleft, swap]},

loop'/.tip={Glyph[glyph math command=looparrowleft]},

 weird/.tip={Glyph[glyph math command=Rrightarrow, glyph length=1.5ex]},

  pi/.tip={Glyph[glyph math command=pi, glyph length=1.5ex, glyph axis=0pt]},

}



begin{document}

  begin{tikzcd}

    A ar[r]        & B \

    G ar[u, hook]

      ar[ur, loop-math to] & \

      % this arrow^ does not have the loop tail

      % instead produces an arrow from G to G.

  end{tikzcd}

  Thank you! I looked right at that section, saw the pi arrows, chuckled, and shrugged, glossing right over the answer in front of me.

  A follow-up. Defining the math to tip is not necessary, replacing loop-math to with loop-> produces arrows, and doesn't have stem-edge alignment problems at strange angles. Something the manual doesn't have (and I don't see a clear easy way to do) is how to define loop' analogous to hook'.
