TikZ: Coordinate on shape vertices

I know that I can draw a rectangle with tikz using draw (0.0,0.0) rectangle (1.0,1.0);
. Is there a possibility to determine all 4 edge coordinates directly from the shape?
I do can save the lower left coordinate and the upper right by draw (0.0,0.0) coordinate (lb) rectangle (1.0,1.0) coordinate (ru);
. But is there a way to get the upper left and bottom right corner directly from the shape?
I know I can calculate them. But are they directly accessible from the shape?
MWE
documentclass{standalone}
usepackage{tikz}
usetikzlibrary{calc}
begin{document}
begin{tikzpicture}
% the rectangle
draw (0.0,0.0) coordinate (lb) rectangle (1.0,1.0) coordinate (ru);
% coordinates
draw (lb) circle [radius=2pt];
draw (ru) circle [radius=2pt];
% calculated coordinates
draw[dashed] (lb |- ru) coordinate (lu) circle [radius=2pt];
draw[dashed] (lb -| ru) coordinate (rb) circle [radius=2pt];
end{tikzpicture}

You could define your own rectangle path. In the MWE
documentclass[tikz,border=3.14mm]{standalone}
begin{document}
begin{tikzpicture}[my rectangle/.style={to path={
-| coordinate[pos=0.5] (#1-2) (tikztotarget) coordinate (#1-3)
-| coordinate (#1-4) (tikztostart) coordinate (#1-1) }}]
draw (0,0) edge[my rectangle=krtek] (1,1);
foreach X in {1,...,4}
{draw (krtek-X) circle [radius=2pt];}
end{tikzpicture}
end{document}
the style my rectangle=<coordinate base name>
will give the four corners the names coordinate base name-1
, ... , coordinate base name-4
.
And there are, of course, predefined shapes that have the corner coordinates stored in anchors.
documentclass[tikz,border=3.14mm]{standalone}
begin{document}
usetikzlibrary{shapes.geometric}
begin{tikzpicture}
% the rectangle
path (0,0) node[draw,anchor=south west,minimum size=1cm] (R) {};
foreach X in {45,135,225,315}
{draw (R.X) circle [radius=2pt];}
path (2,0) node[draw,anchor=south west,minimum size={sqrt(2)*1cm},regular polygon,regular
polygon sides=4] (poly) {};
foreach X in {1,...,4}
{draw (poly.corner X) circle [radius=2pt];}
end{tikzpicture}
end{document}

If you don't want to explicitely declare coordinates for the corners, you can automatically convert your rectangle into a node
with fit
library. This way, the resultant node gives you all rectangular anchors without havint to name them.
Following example shows how to insert rectangular coordinates into fit
parameter. The result node is equivalent to previously drawn rectangle (you don't need to draw the previous rectangle, it's just for demonstration purposes).
documentclass[tikz,border=2mm]{standalone}
usetikzlibrary{fit}
begin{document}
begin{tikzpicture}
draw (0,0) rectangle (2,1);
node[fit={(0,0) (2,1)}, inner sep=0pt, draw=red, opacity=.5] (a) {};
foreach i in {north east, north west, south east, south west}
draw (a.i) circle(2pt);
end{tikzpicture}
end{document}
