Unsafety of create_shader_module_unchecked

[nanoqsh]

I found the create_shader_module_unchecked method and I wonder, can I use this eliminate runtime checks? How significant is this?

I could write something like:

let shader = if cfg!(debug_assertions) {
    device.create_shader_module(desc)
} else {
    // Safety: I assume that all shaders are written correctly
    unsafe { device.create_shader_module_unchecked(desc) }
};

But a few questions remain: What exactly is the unsafety if it's running on GPU, can I just get the wrong result, or can it potentially break something, for example overwrite some neighboring texture? Or can undefined behavior somehow spread to Rust code?
