pub unsafe static NSErrorFailingURLStringKey: &'static NSStringAvailable on crate features
NSURLError and NSString only.Expand description
The NSError userInfo dictionary key used to store and retrieve the NSString object for the URL which caused a load to fail.
This constant is deprecated in Mac OS X 10.6, and is superseded by NSURLErrorFailingURLStringErrorKey. Both constants refer to the same value for backward-compatibility, but the new symbol name has a better prefix.
