Do you mind leaving this PR pending for a few days... There're some structural changes that i want to make first. And the state management is too much relying on the global variables (Thus the |

I think this PartialEq is very weird... Do you think make it a method is a better idea?

More precisely, it’s symmetric but not transitive, so you shouldn’t implement PartialEq this way.

PartialEq actually doesn't have to be transitive, Eq have to be. But it's still better to not hide these kind of logic under equal operator。

line cap and line join can be turned into enum in a future pr.

i'm not very happy with the Mutex here. Can we add a struct called PdfDev or pdf_dev and collect these global states within it. and make the drawing invocations its method? (might be a big change to the code base)

Helpful for seeing which statics are linked to by C++:
rg 'static mut (\w+):' myfile -o -r '$1' | xargs -n1 -I {} sh -c 'echo {} && rg -F {} c_sources_directory'Generally this helps for moving definitions out of extern “C” when they don’t need to be in one.

I thought about this variant too. The problem as you say, it is a big change. And most likely we will be able to do this at one of the last steps of "oxidation".

Mutex moved to start of file. Comment added.

Let's merge it, i think. |
