I have been working on a winit graphics application in Rust on MacOS. My default stack size based on the linker (ld) appears to be 8MB.
What I would like to know is:
1. How common is it for graphics applications etc. to have to increase the default stack size on their target systems? Should 8MB be reasonable?
2. I know on MacOS I can't run this as a child thread, I guess the windowing library doesn't support child thread event loops. If a larger stack size is reasonable, what is the best platform independent way of configuring it in Rust? The only way I have gotten the project to build is to call cargo rustc -- -C link-args=-Wl,-stack_size,0x100000000 after the dependencies have been built. If I create a .cargo/config file with the above option, dependencies like libc fail saying that setting stack size as a linker parameter only works for binaries.
My attempt at a .cargo/crate:
[build]
rustflags = ["-C", "link-args=-Wl,-stack_size,0x100000000"]
The resulting error:
Compiling libc v0.2.68
error: linking with `cc` failed: exit code: 1

= note: ld: -stack_size option can only be used when linking a main executable
clang: error: linker command failed with exit code 1 (use -v to see invocation)
