Module utils 

Shared utilities.

The framework-agnostic helpers (FourCharCode, ffi_string_*, completion handlers, panic-safe wrappers) now live in apple_cf::utils and are re-exported here for backward compatibility.

error.rs is intentionally NOT migrated — it carries SCStream-specific error variants that don’t belong in the framework-agnostic foundation.

Modules

completion

Synchronous completion utilities for async FFI callbacks

error

ffi_string

FFI string helpers that free bridge-owned strings. FFI string utilities — back-compat shim over doom_fish_utils::ffi_string.

four_char_code

Minimal FourCharCode implementation for pixel formats and color conversions

panic_safe

Panic-safety helpers for the C ABI boundary.

Structs

FourCharCode

FourCharCode represents a 4-character code (used in Core Video/Media)
