// MARK:- Pointer type shims
// This section of the code handles shims that change uint8_t* pointers to
// void *s. This is done because Swift does not have the rule that C does, that
// pointers to uint8_t can safely alias any other pointer. That means that Swift
// Unsafe[Mutable]RawPointer cannot be passed to uint8_t * APIs, which is very
// awkward, so we shim these to avoid the need to call bindMemory in Swift (which is
// wrong).
//
// Our relevant citation is: https://github.com/apple/swift-nio-extras/pull/56#discussion_r329330295.
// We want this to land: https://bugs.swift.org/browse/SR-11087. Once that lands we can remove these
// shims.
