  For what it's worth, the symbol does not seem to exist in unicode. Unless they have given it a really counter-intuitive name.

The stmaryrd font has mapsfromchar:

documentclass{article}

usepackage{amsmath}

usepackage{stmaryrd}



newcommand{Rightarrowbar}{Rightarrowmapsfromchar}

newcommand{Leftarrowbar}{mapstocharLeftarrow}



begin{document}



$aRightarrowbar b$



$aLeftarrowbar b$



end{document}

If stmaryrd is not an option for you, it's possible to reflect mapstochar:

documentclass{article}

usepackage{amsmath}

usepackage{graphicx}



newcommand{fakedmapsfromchar}{%

  mathrel{mathpalettereflectmathcharmapstochar}%

}

makeatletter

newcommand{reflectmathchar}[2]{%

  reflectbox{$m@th#1#2$}%

}

makeatother



newcommand{Rightarrowbar}{Rightarrowfakedmapsfromchar}

newcommand{Leftarrowbar}{mapstocharLeftarrow}



begin{document}



$aRightarrowbar b$



$aLeftarrowbar b$

Something like this?

documentclass{article}

usepackage{mathtools}



newcommand{myRightarrow}{mathrel{{Longrightarrow}!vcenter{hbox{$scriptscriptstyle|$}}}}



begin{document}



$ A myRightarrow B$



end{document} 

Edit:
If you want the final bar to have the same width as the Rightarrow, you can use two consecutive | with some kerning between them:

newcommand{myvarRightarrow}{mathrel{{ =⇒ }!vcenter{hbox{$ scriptscriptstyle|mkern-5.4mu|$}}}}

  Doesn't this have uneven stroke widths due to scaling the bar part?

One can always build a symbol by himself (thanks to samcarter, this is a scalable version):

documentclass[margin=1mm]{standalone}

usepackage{graphicx}

usepackage{amssymb}

newcommand{yoursymbol}{mathbin{Rightarrowhspace{-0.45em}vcenter{hbox{scalebox{0.8}{$shortmid$}}}}}

begin{document}

$1yoursymbol2$ {Huge $1yoursymbol2$}

end{document}

Caution: This doesn't work in subscript. I'm trying to find some solution...

  If you use a unit that scales with the font, this will also work with other font sizes. For example hspace{-0.45em} instead of hspace{-4.3pt}

One can always build a symbol by himself (thanks to samcarter, this is a scalable version):

documentclass[margin=1mm]{standalone}

usepackage{graphicx}

usepackage{amssymb}

newcommand{yoursymbol}{mathbin{Rightarrowhspace{-0.45em}vcenter{hbox{scalebox{0.8}{$shortmid$}}}}}

begin{document}

$1yoursymbol2$ {Huge $1yoursymbol2$}

end{document}

Caution: This doesn't work in subscript. I'm trying to find some solution...
