Crate apple_cf 

apple-cf — safe, dependency-free Rust bindings for Apple’s shared Core* frameworks.

This crate is the foundation of the doom-fish macOS Rust suite. It exists so framework-agnostic types like cg::CGRect, iosurface::IOSurface, and dispatch_queue::DispatchQueue don’t have to be re-vendored by every crate that builds on top of CMSampleBuffer/CVPixelBuffer/etc.

Modules

Module	Framework	Feature flag
cf	Core Foundation value, collection, locale, formatter, and runtime wrappers	—
raw	Exhaustive low-level CoreFoundation/CoreMedia/CoreVideo/IOSurface/Dispatch bindings	—
cg	CoreGraphics value types + bitmap drawing wrappers	cg
iosurface	IOSurface (zero-copy GPU buffers)	iosurface
dispatch_queue	Grand Central Dispatch	dispatch
cm	CoreMedia time / sample / buffer wrappers	cm
cv	CoreVideo pixel-buffer wrappers	cv
utils	shared FFI helpers (always on)	—
