* KVC Caching Implementation * Do not ignore struct name when comparing type encoding as NSPoint and NSSize have the same layout * Use fast-path when using Objective-C 2 * Guard old ValueForKey function when using the fast-path * Add basic NSKeyValueCoding tests * Update Copyright Years * NSKeyValueCoding+Caching: Add Versioning to IVar Slot * safe_caching: Remove Guards * Add type encoding helper header * Rename geometry structs (NSRect, NSPoint, NSSize) for toll-free bridging with CoreGraphics * Move CG struct definitions to CFCGTypes.h * Update known struct encoding prefixes * Windows 64-bit is LLP64 and not LP64 * Re-order to avoid complier warning --------- Co-authored-by: rfm <richardfrithmacdonald@gmail.com>

* Type-encoding for known structs in Foundation and CoreGraphics.
|
|
* From macOS 14.4.1 23E224 arm64:
|
|
|
|
* @encoding(NSRect) -> {CGRect={CGPoint=dd}{CGSize=dd}}
|
|
* @encoding(CGRect) -> {CGRect={CGPoint=dd}{CGSize=dd}}
|
|
* @encoding(NSPoint) -> {CGPoint=dd}
|
|
* @encoding(CGPoint) -> {CGPoint=dd}
|
|
* @encoding(NSSize) -> {CGSize=dd}
|
|
* @encoding(CGSize) -> {CGSize=dd}
|
|
* @encoding(NSRange) -> {_NSRange=QQ}
|
|
* @encoding(CFRange) -> {?=qq}
|
|
*
|
|
* Note that NSRange and CFRange are not toll-free bridged.
|
|
* You cannot pass a CFRange to +[NSValue valueWithRange:]
|
|
* as type encoding is different.
|
|
*
|
|
* We cannot enforce this using static asserts, as @encode
|
|
* is not a constexpr. It is therefore checked in
|
|
* Tests/base/KVC/type_encoding.m
