This plugin uses the new RenderLayer API added in 5.0 to visually replace the sized C number types with their Rust equivalents in HLIL for easier readability.
Example: (int64_t => i64)
As this is a purely visual change, it costs us nothing and breaks nothing else.
Simply tick the Oxidize Types entry in the Render Layers section of the Burger Menu.
Note to the author of the Type Oxidizer plugin: I really want to try whatever you were smoking, it must have been really good.
The function signature in the locked bar at the top of the BinaryView (that appears when the current function signature is not in view) can not be modified via the RenderLayer API at this time. It will hopefully be added soon, at which point this plugin will be updated.
I have been informed that this is not planned and therefore, as far as I'm aware, there is nothing I can do about it at this time.
